[GitHub] [airflow] potiuk opened a new pull request #17524: Decreases cassandra memory requirement during Integration tests

URL: https://github.com/apache/airflow/pull/17524
Seems that Cassandra was the main reason why a lot of memory
was used during our integration tests. This has been overlooked
before but seems that cassandra will always take as much as 25%
of available memory by default and it meant for the GitHub public
runners it was ~2 GB. Also for the self-hosted runners, even if
they had a lot of memory, cassandra could eat up big chunk of the
memory.
With the settings added in PR Cassandra will take ~750 MB of memory
total.

This **might** be the reason why some of our tests for GitHub Public runner die with a sudden death sometimes and we have no logs for it. Let's merge and see.

The PR most likely needs to run full matrix of tests because it modifies parts of the core of Airflow. However, committers might decide to merge it quickly and take the risk. If they don't merge it quickly - please rebase it to the latest main at your convenience, or amend the last commit of the PR, and push it with --force-with-lease.
