What

This will allow user to submit statement without an explicitly specified compute pool (CP). Instead, backend will provision a “default” compute pool (DCP) that is created and managed on the user’s behalf.

Blast Radius

Flink statement create and flink compute pool commands could be affected for existing as well as new behaviour.

Pull Request Overview

This PR adds support for Flink default compute pools, allowing users to submit Flink statements without explicitly specifying a compute pool. The backend will provision a default compute pool managed on behalf of the user.

Key changes:

• Introduced confluent_flink_compute_pool_config resource and data source for managing default compute pool configuration
• Added default_pool attribute to confluent_flink_compute_pool resource and data source
• Made flink_compute_pool_id optional in provider configuration, reducing required attributes from 7 to 6 (non-OAuth) and 5 to 4 (OAuth)
