[LI-HOTFIX] Improving performance of the isReplicaOnline method (#206)#271
Merged

…he#206) TICKET = LIKAFKA-38536 LI_DESCRIPTION = The ControllerContext.isReplicaOnline method is frequently called inside a loop, and internally this method relies on several derived fields in the ControllerContext. Repeatedly calculating the derived fields could be expensive, and yet these fields do not change between iterations of the loop. This PR creates a new class ControllerContextSnapshot that tries to cache the derived fields in order to save the repeated computation and speed up the controller. EXIT_CRITERIA = When this change is proposed in upstream kafka and pulled internally.

Original hotfix PR #206
The ControllerContext.isReplicaOnline method is frequently called inside a loop,
and internally this method relies on several derived fields in the ControllerContext.
Repeatedly calculating the derived fields could be expensive, and yet these fields
do not change between iterations of the loop.
This PR creates a new class ControllerContextSnapshot that tries to cache
the derived fields in order to save the repeated computation and speed up the
controller.
