[2024-02-07T10:47:31,387][INFO ][%iinrt_dosor_0%lease-updater-1][LeaseUpdater]
Leases updated (printed once per 10 iteration(s)):
[inCurrentIteration=LeaseStats [leasesCreated=3, leasesPublished=0,
leasesProlonged=0, leasesWithoutCandidates=0], active=0,
currentAssignmentsSize=3].{code}
* {*}inCurrentIteration{*}: leases that were processed in the iteration of
LeaseUpdater that printed this log message. {*}leasesCreated{*}: how many
leases were created (and negotiation started), {*}leasesPublished{*}: how many
of them were published after successful negotiation, {*}leasesProlonged{*}: how
many were prolonged, {*}leasesWithoutCandidate{*}: leases that had to be
created or prolonged but there was no leaseholder candidate for them.
* {*}active{*}: active leases (accepted and not outdated)
* {*}currentAssignmentsSize{*}: total assignments list size, that is processed
(number of replication groups).

> , test failure of
> {{{}org.apache.ignite.internal.raftsnapshot.ItTableRaftSnapshotsTest:
> leaderFeedsFollowerWithSnapshot{}}}, we see that there are no log messages on
> replica about lease negotiation, which means that it didn't even started on
> the placement driver active actor's side. But the active actor has started
> before. Log doesn't provide any information about the detail what happened on
> LeaseUpdater.
> The suggestion is to add logging to know whether some exception happened in
> {{{}updateLeaseBatchInternal{}}}, or in {{{}LeaseNegotiator#negotiate{}}},
> and logging of lease updating statistics (how many groups without
> leaseholders were detected, how many negotiations are in progress, how many
> leases are prolonged).
