Subject [jira] [Created] (IGNITE-12351) Append additional cp tracking activity - pages sort.
Date Tue, 05 Nov 2019 12:05:00 GMT
Vladimir Malinovskiy created IGNITE-12351:
---------------------------------------------

             Summary: Append additional cp tracking activity - pages sort.
                 Key: IGNITE-12351
                 URL: https://issues.apache.org/jira/browse/IGNITE-12351
             Project: Ignite
          Issue Type: Bug
            Reporter: Vladimir Malinovskiy
            Assignee: Vladimir Malinovskiy


CheckpointMetricsTracker has no info about _splitAndSortCpPagesIfNeeded_ stage, thus in case
of huge number of dirty pages someone can observe in log:
10:08:00 checkpoint started
10:10:00 checkpoint finished
<--- ?? 
10:10:20 checkpoint started

if checkpointFrequency = 30000 and all tracker durations: beforeLockDuration, lockWaitDuration
gives no clue what kind of work (20 sec) Checkpointer thread is waiting for.

Additionally (hope this is not big deal) need t obe fixed redundant effectivePageId computation
cause FullPageId already has effectivePageId info.

 

{{return Long.compare(PageIdUtils.effectivePageId(o1.pageId()),
                        PageIdUtils.effectivePageId(o2.pageId()));}}

writeCheckpointEntr() duration should also be logged.
