The threading changes look OK to me, can you describe more in the PR why the things removed from the pause/resume handling were unnecessary? I don't think I understood that part |
@jon-wei thank you for the review. I've updated the PR description. |

Fixes #5729.
Mainly, I removed
publishQueue
andpublishExecService
fromIncrementalIndexingKafkaTaskRunner
which caused #5729. Instead,AppenderatorDriver
(and thusAppenderator
APIs are called by the same thread. SeepublishAndRegisterHandoff()
.I additionally removed some unnecessary or unused variables.
pauseAfterRead
fromKafkaIOConfig
because it was alwaysfalse
.pauseMillis
fromIncrementalIndexingKafkaTaskRunner
andtimeout
parameter from thepause()
api. Those two variables are designed only forpauseAfterRead
. Since that parameter is not used,pauseMillis
was alwaysPAUSE_FOREVER
andtimeout
was always 0.resume
parameter fromsetEndoffsets()
api. This parameter was also used only forpauseAfterRead
and alwaystrue
.Also,
setOffsets()
API now returnsINTERNAL_SERVER_ERROR
on failure.This change is
