Creating a stream in Data Streams

1. In the management console, select the folder to create a data stream in.

2. Select Data Streams.

3. Click Create stream.

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

5. Enter a name for the stream. The naming requirements are as follows:

   • It must be from 2 to 63 characters long.
   • It may 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.

9. Select data storage settings:

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