This task involves modifying the swatch-contracts service to consume messages from the "platform.rhsm-subscriptions.tally" topic in batches.

The changes will include:

• Configure swatch-contracts to consume messages from the platform.rhsm-subscriptions.tally topic in configurable batches. The new consumer must be configured using the following property:

mp.messaging.incoming.tally-in.auto.offset.reset=latest

This is the default configuration, but it's better to be explicit here. The idea is to only consume the new messages.

• Capacity Query Optimization: For each batch of consumed messages, a single query will be executed to retrieve the necessary capacity information using the existing "subscription_capacity_view". This will reduce the load on the database or external service providing capacity data.

• Batch Response Sending: After processing the capacity for the entire batch, a corresponding batch of responses will be sent to the platform.rhsm-subscriptions.utilization topic.

Acceptance Criteria

• Added new data model called UtilizationSummary that includes the snapshot summary data plus the capacity data from the query
• New component tests are implemented to verify the end-to-end batch processing functionality
