Migrate to Polaris from Rockset

This guide walks through the process to seamlessly migrate your data to Imply Polaris on AWS from Rockset.

The following diagram demonstrates the end-to-end process of the migration to Polaris. Shaded boxes represent steps taken within Polaris, and unshaded boxes represent steps taken outside Polaris, either in AWS or Rockset.

Sign up for Polaris​

If you haven't already, sign up for a Polaris trial. You need a Polaris organization to host your Rockset data.

Optionally, run through the Polaris quicksart to learn about Polaris's features.

Create a staging S3 bucket​

Launch the AWS Management Console and create an S3 bucket to stage your data. To ensure you assign the correct permissions to your bucket, refer to Rockset's example IAM policies.

Export your data to S3​

Login to Rockset and use the INSERT INTO s3 function to export your data to the staging bucket you created.

For best results export your data in Parquet format.

Import your data into Polaris​

Follow the steps in Connect to Amazon S3 to create a connection from Polaris to S3. Use the example IAM permissions policy to ensure you assign the correct permissions for Polaris.

Refer to the Guide for Amazon S3 ingestion for detailed instructions.

The Imply team can help with ingestion if you need it.

Connect your client​

You can run queries against your data in Polaris using the SQL workbench.

When you're ready to connect your client applications, you can use the following APIs:

You can also connect a number of third-party business intelligence tools.

Migrate your queries​

Rewrite your Rockset queries using Druid SQL. Then submit them to Polaris using the Query API.

If you need assistance, the Imply team will help you migrate your queries.
