Supported databases

Connectivity policy

Analyst Studio currently supports connectivity to customer data using Java Database Connectivity (JDBC) drivers. Analyst Studio does not write JDBC drivers. We contract the use of proprietary JDBC drivers or use established and well-supported open-source JDBC drivers.

For Preferred and Supported databases, Analyst Studio ensures functionality for all versions of the database server currently actively maintained by the database vendor. Analyst Studio does not ensure continued functionality for database server versions that have reached end of life, or for database types that are not explicitly supported.

Analyst Studio will usually support or recommend only one driver per database type. However, to give customers flexibility during their update process, we will enable customers to use either the recommended or the most recent version until the next update (either 6 or 12 months). Analyst Studio will usually provide 6 months' notice to customers before driver removal, although we reserve the right to remove drivers with known security issues on less notice.

Driver deprecation

Analyst Studio will mark for deprecation and set removal dates for older versions of drivers. We generally set removal dates for the oldest drivers 6 months out, when adding new versions of drivers.

Drivers that are past their removal date cannot be used to connect to Analyst Studio. The removed driver will no longer be available in the Preferred JDBC driver dropdown of the connection’s details.

On the removal date, any connections still using that driver will be updated by Analyst Studio to use the latest recommended driver. This may cause connectivity issues. Analyst Studio encourages customers to update their preferred drivers shortly following announced updates.

Support levels

For the listed database types below, Analyst Studio aims to support all versions of the database actively supported by the database vendor or appropriate open-source community.

Tier 1: Preferred

These database and integration types are fully supported by Analyst Studio and drivers are upgraded at least semi-annually. We are committed to improving the experience of users connecting Analyst Studio to data sources of these types, and will fix issues based on severity and demand.

Driver Known Issue Further Details

Simba v 2.0.27.1001

Queries with special characters failing

Queries with special characters (for example, ‘√ß’ and ‘√Ö’) are failing with String index out of range error. As a workaround, use the previous version of the driver (2.0.23.1000).

Simba v 2.0.13.1000

Requires additional IAM permissions for queries

This version of the driver requires that the Analyst Studio user’s IAM permissions include the athena:ListDataCatalogs permission. This permission is required for query execution via Analyst Studio (not just the Schema Browser).
Customers whose Analyst Studio user is managed via the AmazonAthenaFullAccess Managed Policy will not experience issues.

Simba v 2.0.13.1000

Schema refreshes fail with Null Pointer Exception for external data sources

Attempts to get or update schemas when Athena is connected to non-Hive (PostgreSQL confirmed) external data sources results in a Null Pointer Exception. For customers whose Athena instance includes external data sources, automatic refresh of the database’s schema data should be disabled and the Analyst Studio Schema Browser will be unable to display data.
Database configuration instructions

The Analyst Studio user’s IAM permissions must include athena:ListDatabases and athena:ListDataCatalogs. In addition, ensure that port 444 is open to outbound traffic.

Apache Avatica 1.17.0

6/21/2020

The following are known issues with the current supported drivers. Analyst Studio continues to advocate on our customers' behalf for vendors and open-source communities to resolve these issues.

Driver Known Issue Further Details

Avatica 1.17.0

Druid fetch size limited to 100

Druid JDBC driver only returns 100 rows per batch, resulting in longer-than-expected query response times. There is a server-side fix that can be applied.

Avatica 1.17.0

Druid Basic Authentication is unsupported

Analyst Studio currently requires Druid connections over Bridge.

Avatica 1.17.0

Connection context properties are unsupported

Analyst Studio currently does not support changing the Druid broker’s setting for the connection via JDBC properties.

Avatica 1.17.0

Only Druid SQL support

When connecting to Druid via JDBC, only Druid SQL syntax is supported. Native (json-type) query syntax will result in errors.

Avatica 1.17.0

Druid SQL limitations

Not all Druid features are supported via Druid SQL and JDBC connectivity. Please see the Druid docs.

Avatica 1.17.0

Single Schema Support

Analyst Studio’s Schema Browser will surface only tables found in the default druid schema.

Avatica 1.17.0

Query cancellation is unsupported

Druid supports cancellation for native (json-type) queries, but not for Druid SQL queries. If users attempt to cancel a query in the Analyst Studio UI, the query run will not be interrupted. The driver does not return an error, so Analyst Studio is unable to surface anything to the user.
Connecting to Analyst Studio

When connecting Druid to Analyst Studio, fill out the connection form as follows:

  1. Display name: the name of the connection used in the Schema Browser.

  2. Description: optional additional context viewable in Connection Management.

  3. Host: the route of the Druid cluster Broker, as specified in the broker/runtime.properties file.

  4. Port: the port of the Broker. The default port is 8082. If your cluster is secured by SSL, the default port is 8182.

  5. Preferred JDBC Driver: the Avatica 1.17.0 driver is the only current driver.

  6. Disable transport encryption: Analyst Studio strongly recommends that transport encryption be enabled and that Druid be configured to use TLS v.1.2. If disabled, connections between the Bridge connector and your database will not be encrypted.

Please note the following limitation of broker connection stickiness over JDBC:

"Druid’s JDBC server does not share connection state between Brokers. This means that if you’re using JDBC and have multiple Druid Brokers, you should either connect to a specific Broker, or use a load balancer with sticky sessions enabled. The Druid Router process provides connection stickiness when balancing JDBC requests, and can be used to achieve the necessary stickiness even with a normal non-sticky load balancer."

Driver Known Issue Further Details

Simba v 2.6.17.1021

Does not support Unity Catalog

Please use v 2.6.21.1039 or newer to utilize Unity Catalog.

Simba v 2.6.17.1021

Dates return incorrectly prior to 10/15/1582

When using Spark 2.4.4 to Spark 3.0, DATE and TIMESTAMP data before October 15, 1582 may be returned incorrectly if serializing query results using Apache Arrow.
As a workaround, add EnableArrow=0 in your connection URL to disable the Arrow result set serialization feature.

Simba v 2.6.17.1021

Does not support Spark version 2.1

The driver no longer supports servers that run Spark version 2.1.

Simba v 2.6.17.1021

Strings in Binary Columns

Queries return binary results (not strings) for binary datatype columns.
For example, if I insert "hi" in a binary column, where I previously would see "hi" returned by the driver, I now see "6869".

Simba v 2.6.17.1021

Deprecated Versions

Support for Spark 1.6, 2.1, and 2.2 is deprecated, and will be removed in a future release of this driver. The driver only supports connections to Spark Thrift Server instances. It does not support connections to Shark Server instances.
Gather JDBC connection parameters

Connecting to Databricks requires a running Spark cluster configured with SSL enabled and using HTTPS as the underlying thrift protocol (this is the default configuration for new clusters).

Connecting to Analyst Studio

  1. Follow these steps to connect a Databricks database. Change the display name to something that helps you recognize the database behind the connection.

  2. Fill in the host, token, and HTTP path fields with the information you gathered above.

  3. Click Connect to save the new connection.

Supported SQL dialect

Analyst Studio supports connecting to Databricks clusters via their embedded Hive server using Hive’s open-source JDBC driver. This restricts the supported SQL dialect to HiveQL; we currently do not support querying in Spark SQL, though we may add support for it at a later date.

Automatic cluster termination

Databricks "Standard" Spark clusters are configured by default to automatically terminate after 120 minutes of inactivity. The Hive JDBC driver cannot trigger the cluster to automatically restart, so you may want to adjust the timeout or disable automatic termination per Databricks' documentation. If the driver attempts to connect to the server after it’s been shut down, the connection attempt will fail until the cluster is restarted manually.

Unity Catalog

Analyst Studio has added three level namespace support (catalog.schema.table) for Databricks to support Unity Catalog. The catalog and schema are now concatenated at the top level in the Schema Browser.

Driver Known Issue Further Details

Simba v 1.3.2.1003 and older

Nullpointer exceptions

This driver is known to cause null pointer exceptions (for example, when a table has unicode column names) so will be removed and replaced with the newest version where this issue is fixed.

Simba v 1.2.23.1027 and older

Does not support JSON format

Please utilize 1.3.0.1001 or newer versions to work with JSON data.

Simba v 1.2.21.1020

Read timed out error

Queries occasionally encounter a read timed out error.
The driver introduced this error after changing how timeouts work, but fixed in the subsequent version.
Analyst Studio is still confirming the fix, and suggests using an older version if issue still persists.

Simba v 1.2.16.1020

DDL/DML commands in comments

Null pointer exception when using DDL/DML commands (for example, create, update) in single line comments (for example — services created and deleted by month). As a workaround, use the /* */ format.

Simba v 1.2.16.1020

Large queries need the 'bigquery.readsessions.create' permission

Large queries trigger the Google Storage API, which is free to use for anonymous tables, but requires admins to add the 'bigquery.readsessions.create' to their Google Big Query role associated with the Analyst Studio DB connection.

java.sql.SQLException: [Simba] BigQueryJDBCDriver 100210 Error initializing the Storage API. +

Simba v 1.2.11.1014

Batch priority is unsupported

The specification of job priority is unsupported. All queries are executed as "interactive" priority, never "batch" priority.
Google Big Query batch priority is described here: https://cloud.google.com/bigquery/docs/running-queries#batch.

Simba v 1.2.11.1014

Necessary permissions

To connect via this driver, the service account should have the roles BigQuery Data Viewer and BigQuery Job User.
In addition, the Analyst Studio GBQ service account must have the bigquery.jobs.list permission. This permission can be added via several roles. Analyst Studio recommends either BigQuery Resource Viewer or BigQuery User, although broader access will also function.
The Analyst Studio user would additionally need BigQuery Data Editor role if the queries users execute from Analyst Studio are expected to be able to write to the database (for example, DROP, CREATE, UPDATE). Temporary functions use and temporary table creation and deletion do not require this permission.
Database configuration instructions

To connect Analyst Studio to your BigQuery project, you will need to create a service account for Analyst Studio to use.

  1. Navigate to the Google Developers Console. Before proceeding, click on the dropdown to the right of Google Cloud and select the project to which you want to connect.

    If you do not see the project you would like to connect to listed in the dropdown, click on the account switcher in the upper right corner of the window and ensure you are logged in to a Google account that is a member of the project.

  2. Click on the hamburger menu in the upper left and select IAM & Admin and then Service accounts. Click the Create service account button.

    BigQuery

  3. Give your new service account a name, pick a unique ID, and add a description. Click Create and continue.

    BigQuery

  4. Grant required roles, for example, BigQuery Job User and BigQuery Data Viewer.

    BigQuery

  5. Finally, click Done to create your service account. Now we create the JSON key file. Navigate to Manage keys under the Actions menu for the service account.

    BigQuery

  6. Navigate to ADD KEY > Create new key.

    BigQuery

  7. Click CREATE to create and download the JSON key file. Save the private key file to a secure place where you can easily retrieve it when setting up the connection in Analyst Studio.

    BigQuery

  8. Return to Analyst Studio, and begin the process to connect a BigQuery database. When you see the form to enter your BigQuery credentials, first enter a name (internal to Analyst Studio) for the new database connection.

  9. In the Project ID field, enter the BigQuery project ID. It can be found in the URL of your Google Developers Console. The URL should be structured like this:

     https://console.developers.google.com/apis/library?project=MY_PROJECT_ID

  10. In the Service Account Email Address field, add your service account’s email address that you noted in step 3.

  11. Under the Key field, click Choose File and select the private key file you downloaded in step 6.

  12. Click Connect to complete the connection.

Standard vs. legacy SQL

When connecting to BigQuery, you will choose either legacy SQL or standard SQL as the default SQL dialect for that connection. Most users choose standard SQL, which is similar to industry standard SQL dialects used by other databases.

Regardless of your choice as the connection’s default, users can specify which dialect they would like to use on a query-by-query basis by including either #standardSQL or #legacySQL in the Query Editor.

A Workspace admin can change the default SQL preference of a BigQuery connection at any time by following these steps:

  1. Click the app switcher icon in the top navigation bar and select Analyst Studio.

  2. Click on your name in the upper left corner of the window.

  3. Click Workspace Settings.

  4. Under the Data section, click Connections.

  5. Click on the BigQuery connection you want to update.

  6. In the upper right corner of the page, click on Settings.

  7. Toggle standard SQL on or off.

  8. Before your settings are updated, you will need to re-upload your service account’s P12 key. Learn more about BigQuery service accounts and P12 keys.

  9. Click Save Changes.

    Take care when changing the default SQL dialect for an existing connection, as any queries written using that connection that are written in the previous default SQL dialect may no longer work.
Connecting to Analyst Studio

  1. Return to Analyst Studio, and begin the process to connect a BigQuery database. When you see the form to enter your BigQuery credentials, first enter a name for the new database connection.

  2. In the Project ID field, enter the BigQuery project ID. It can be found in the URL of your Google Developers Console. The URL should be structured like this: https://console.developers.google.com/apis/library?project=MY_PROJECT_ID.

  3. In the Service Account Email Address field, add your service account’s email address that you noted in step 4.

  4. Under the Key field, click Choose File and select the private key file you downloaded in step 3.

  5. Click Connect to complete the connection.

Use BigQuery to query Google Sheets

You can use Analyst Studio to query Google Sheets in BigQuery. The first step, enabling your Google Drive API, only needs to be done once.

  1. Enable Google Drive API.

    Navigate to the Google Developer Console and select your project from the project dropdown menu. From the left menu, click on Library. Under Google Apps API, click on Drive API to enable the API from that page.

  2. Create a table in BigQuery from your Google Sheet.

    Go to the BigQuery Web UI. In the navigation, hover over a schema name and click the down arrow icon next to the name. Choose Create new table.

    GoogleSheets

    Select Google Drive for the new table’s location and paste the Google Sheet URL (not the shared link, but the actual URL you use to view the Sheet) into this field. Choose Google Sheets as the Format. Then add all the column names and types from your Google Sheet under Schema. Click Create Table when ready.

    GoogleSheets

  3. Enable Google Sheets for Analyst Studio Use.

    • For Analyst Studio to query your new table, share your Google Sheet with the service account email address you used to connect Analyst Studio to BigQuery. You can also share folders in your drive with this email address, which will allow Analyst Studio to query every sheet in that folder.

    • To get your service account email address, go to your Google Cloud Console, switch to your Project, and click on Service Accounts. Copy the service account email address you used to connect Analyst Studio to BigQuery.

    • To share a sheet or folder, click Share on the Google Sheet or in the folder, and paste the service account email address into the Share email field.

    • Note that BigQuery schemas don’t refresh automatically in Analyst Studio. To see this table appear in your schema browser, go to Workspace Settings and click Connections under the Data section.

Server Timezone Specification is required

Customers without a specified Server Timezone for their databases will see queries fail if any of the time zones (application/database servers) are not in the format UTC+xx or GMT+xx.
Queries will fail with the following error: java.sql.SQLException: The server time zone value 'PDT' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specific time zone value if you want to utilize time zone support.
Note that the error is directly from the JDBC driver. At this time, Analyst Studio does not support customers setting additional configuration properties (such as the suggested 'serverTimezone' property) via the JDBC driver.

Cloud environments

Amazon Web Services

Overview

We have two ways of connecting to your RDS instance depending on your AWS settings. If your instance is publicly accessible, then Analyst Studio can connect directly to it. For databases that are not accessible, you can use the Bridge connector. We’ll start by determining if your database is accessible to us.

Accessibility

  1. Navigate to your RDS Instance Console.

  2. Click the arrow and then magnifying glass to view the details of the instance that you want to connect.

    Amazon RDS Console

  3. Look under Security and Network. Your instance is in a VPC if there’s an entry labeled VPC. It is typically found below Availability Zone and above Security Groups. If you don’t have an entry here, then your instance is not in a VPC, and you can jump to the Security Groups section below.

    RDS with a VPC

  4. Instances in VPCs can be public or private. We can find out by looking under Security and Network again. This time for an entry labeled Publicly Accessible. If it is followed by a Yes, then you can jump to the Security Groups section below.

    RDS on a public VPC

  5. To connect to instances in a private VPC, you’ll need to install our Bridge connector.

Security groups

All connections from Analyst Studio will come from one of the eight IP addresses below. In most cases, you’ll need to add these addresses to your RDS instance’s Security Group. We’ve broken the steps down into two sections: VPC and No VPC. Security Groups in a VPC are managed the same between EC2 and RDS. RDS instances outside of a VPC have a different process.

  • 54.68.30.98/32

  • 54.68.45.3/32

  • 34.209.23.118/32

  • 54.188.241.100/32

  • 52.43.195.103/32

  • 3.224.146.111/32

  • 54.221.238.89/32

  • 52.20.173.236/32

VPC

  1. Under Security and Network, click the security group name.

    Amazon RDS

  2. A new tab will be opened. Click on the Inbound tab and then Edit.

    Amazon RDS

  3. Find the RDS type that matches your instance (for example, PostgreSQL), enter each of our addresses, and then click Save.

    Amazon RDS
No VPC

  1. Under Security and Network, click the security group to which that database belongs.

    Amazon RDS

  2. At the bottom of the page, highlight the Connection Type selector and choose CIDR/IP.

  4. Click the blue Authorize button.

  5. Repeat steps 1-4 for each of the addresses listed above.

FAQs

Q: How to import Analyst Studio results into a Google Sheet

While we currently do not support the ability to natively export or import data to and from a Google Sheet, we do have a step-by-step guide on how to query Google Sheets using BigQuery in Analyst Studio. You can also follow the instructions below for a custom way to import data from an Analyst Studio report to a Google Sheet programmatically.

To enable this feature in a Google Sheet, you can begin by following these steps:

  1. Go to the Analyst Studio report and click View Details.

  2. Click on the query on the left to access the query token in the URL.

  3. Copy the query token from the URL /queries/[QUERY_TOKEN].

  4. Save the formula below somewhere safe because we will need to use it on our final step.

=importModeResult("https://app.mode.com/[WORKSPACE]/reports/[REPORT_TOKEN]/queries/[QUERY_TOKEN]")

In the formula above, please be sure to replace "WORKSPACE" with your workspace name as shown in any report URL, "REPORT_TOKEN" with the report token available in the URL, and "QUERY_TOKEN" with the query token that you just copied.

This formula will import the data from the Analyst Studio query into the Google Sheet once the following steps are completed. It will automatically use the last successful run of the query.

Setup

  • From a Google Sheet, click Extensions -> Apps Script from the top menu bar.

  • In the code editor, overwrite the existing code and paste the importModeResults function below ⬇️ into the code editor. Then, save it via the disk file icon.

    function importModeResult(url) {

var USERNAME = PropertiesService.getScriptProperties().getProperty('username');
var PASSWORD = PropertiesService.getScriptProperties().getProperty('password');

var token = getTokenFromUrl(url);
var account = getAccountFromUrl(url);
var query = getQueryFromUrl(url);

var options = {
  headers: { 'Authorization': 'Basic ' + Utilities.base64Encode(USERNAME + ':' + PASSWORD, Utilities.Charset.UTF_8) }
};

var reportUrl = 'https://app.mode.com/api/' + account + '/reports/' + token;
var reportResponse = UrlFetchApp.fetch(reportUrl, options);
var reportJSON = JSON.parse(reportResponse);

var lastRunPath = reportJSON['_links']['last_successful_run']['href'];
var queryRunUrl = 'https://app.mode.com' + lastRunPath + '/query_runs'
var queryRunResponse = UrlFetchApp.fetch(queryRunUrl, options);
var queryRunJSON = JSON.parse(queryRunResponse);

var queryRuns = queryRunJSON['_embedded']['query_runs']

queryRuns.forEach(function(q) {
  if (q['query_token'] == query) {
    resultPath = q['_links']['result']['href']
  }
})

if (resultPath) {
  var csvPath = 'https://app.mode.com' + resultPath + '/content.csv'
  var csvResponse = UrlFetchApp.fetch(csvPath, options);
  var csvTextRaw = csvResponse.getContentText();
  var csvText = csvTextRaw.replace(/(["'])(?:(?=(\\?))\2[\s\S])*?\1/g, function(e){return e.replace(/\r?|\r/g, '') });

  return Utilities.parseCsv(csvText)

} else {
  return 'Invalid URL!'
}


function getTokenFromUrl(url) {
  return url.split('/reports/')[1].slice(0,12)
}

function getAccountFromUrl(url) {
  return url.split('.com/')[1].split('/')[0]
}

function getQueryFromUrl(url) {
  return url.split('/queries/')[1].slice(0,12)
}
}

  • In the code editor, click the gear icon -> Project Settings in the left-side menu, scroll down to the bottom, and click the Add Script Property tab.

  • Add a separate username and password property. The value of the username property should be an Analyst Studio API token. The value of the password property should be an Analyst Studio API secret. You can create a token and secret in the API Tokens tab of your Analyst Studio settings page. Here’s our documentation on how to generate API tokens.

  • Once you save these properties, navigate back to your Google Sheet and add the importModeResult formula into a cell in your Google Sheet. This will populate the query results.

Q: How to upload data via CSV?

Currently, we do not offer CSV uploads to private connections. Analyst Studio only supports uploading CSVs to our public data warehouse, but please note that this data will be publicly accessible. You can learn more about uploading CSV to the public warehouse here.
