Code Review
This pull request lowers the default value of DEFAULT_ACTOR_MAX_TASKS_IN_FLIGHT_TO_MAX_CONCURRENCY_FACTOR from 4 to 2. This change reduces the default number of tasks that can be queued per actor, which should help reduce memory pressure at the cost of potentially less task pipelining. The change itself is straightforward and seems reasonable. As a side note, I noticed a related test comment in python/ray/data/tests/test_autoscaler.py that refers to the old default value of 4 and could be updated to reflect this change, although that file is not part of this PR.
