Backport of #23248
Cherry-pick of #23248 onto
camel-4.14.x.Original PR: #23248 - Camel 23523 kafka batch interval reset
Original author: @FNaughton
Target branch:
camel-4.14.xOriginal description
Fixes a bug where
intervalWatchis never reset whenexchangeListtransitionsfrom empty to non-empty, unlike
timeoutWatchwhich is reset at that point.After an idle period longer than
batchingIntervalMs, the watch is pre-expired,causing
hasExpiredRecords()to fire on the very next poll that returns records,flushing a prematurely small batch.
Fix: add
intervalWatch.restart()alongsidetimeoutWatch.takenAndRestart()inthe
exchangeList.isEmpty()branch ofprocessExchange().Claude Code on behalf of Claus Ibsen
