[jira] [Updated] (IGNITE-13294) Page write throttling can park
threads for too long
[ https://issues.apache.org/jira/browse/IGNITE-13294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aleksey Plekhanov updated IGNITE-13294:
---------------------------------------
Description:
Page write throttling incorrectly calculate average checkpoint write speed in some circumstances (gets wrong interval for calculation), this leads to parking threads for too long.
Root cause: {{PagesWriteSpeedBasedThrottle.onMarkDirty()}} should not open new interval for {{speedCpWrite}} after {{PagesWriteSpeedBasedThrottle.onFinishCheckpoint()}} until new checkpoint begin.
Reproducer: {{PagesWriteThrottleSmokeTest.testThrottle()}}, currently always failed in master (https://ci.ignite.apache.org/project.html?tab=testDetails&projectId=IgniteTests24Java8&testNameId=2808794487465215609&page=1&branch_IgniteTests24Java8=%3Cdefault%3E)
