Creating a data streamCreating a data stream

Management console
  1. In the management console, select the folder where you want to create a data stream.

  2. Select Data Streams.

  3. Click Create stream.

  4. Specify the Yandex Managed Service for YDB database or create a new one. If you chose to create a new database, click after creating it to refresh the list of databases.

  5. Name the data stream. The naming requirements are as follows:

    • It must be from 2 to 63 characters long.
    • It can only contain lowercase Latin letters, numbers, and hyphens.
    • It must start with a letter and cannot end with a hyphen.
  6. Specify the number of data shards.

    Warning

    You cannot reduce the number of shards for the created stream.

  7. Set the maximum shard throughput. A stream's throughput is equal to the product of the number of shards by the throughput of each of them.

  8. Select a pricing plan (for serverless databases).

  9. Select data storage settings:

    • Size Limit: Specify the maximum data storage size.
    • Time Limit: Specify the maximum data retention period for the stream.
  10. Click Create.

Wait for the stream to start. Once the stream is ready for use, its status will change from CREATING to ACTIVE.
