Upd #1 > SafeTimeReorderingException occurred because of the race between > maxObservableSafeTime update on leader election and SafeTimeSyncCommands > processing within onBeforeApply. In order to fix that > * I've added synchronous onBeforeLeaderStart callback that is now used to > update maxObservableSafeTime with clock.now() +CLOCK_SKEW insread of > previously used asynchronous onLeaderStart. By asynchronous here I mean > asynchronous to onBeforeApply. > * I've also added maxObservableSafeTime update to Long.MAX_VALUE on each > leader stop along with same initial value. MAX_LONG is greater than any > possible safeTime propagated with commands thus we will actually block any > SafeTimeSyncCommands processing (**even within onBeforeApply**) before leader > election that includes proper maxObservableSafeTime initialization. -- This message was sent by Atlassian Jira (v8.20.10#820010)
