[jira] [Updated] (IGNITE-15017) Contention in lock on Compound
future
[ https://issues.apache.org/jira/browse/IGNITE-15017?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vladislav Pyatkov updated IGNITE-15017:
---------------------------------------
Description:
During analyze of JFR I noticed that the threads waiting long time on getting compounds on the future.
It happened on an exclusive checkpoint phase and have a negative impact to transactions (they increased to a hundred milliseconds).
This stack held the checkpoint workers:

You can see that the method {{checkComplete}} was freezed on 272 938 246 microseconds in two times invocations.
