Method Detail

doneBackgroundRead

void doneBackgroundRead(org.apache.jackrabbit.oak.plugins.document.BackgroundReadStats stats)

Report to the collector that a background read was done.

Parameters:

stats - the stats for the background read operation.

doneBackgroundUpdate

void doneBackgroundUpdate(org.apache.jackrabbit.oak.plugins.document.BackgroundWriteStats stats)

Report to the collector that a background update was done.

Parameters:

stats - the stats for the background update operation.

doneLeaseUpdate

void doneLeaseUpdate(long timeMicros)

Report to the collector that a lease update was done.

Parameters:

timeMicros - the time in microseconds it took to update the lease.

doneBranchCommit

void doneBranchCommit()

Report to the collector that a branch commit was done.

doneMergeBranch

void doneMergeBranch(int numCommits,
                     int numChanges)

Report to the collector that a branch was merged.

Parameters:

numCommits - the number of branch commits merged.

numChanges - the number of changes merged.

doneMerge

void doneMerge(int numChanges,
               int numRetries,
               long timeMillis,
               long suspendMillis,
               boolean exclusive)

Reports to the collector that a merge was done. The number of changes reported with this method is the number of documents that were modified with the merge.

Parameters:

numChanges - the number of changes in this merge.

numRetries - the number of retries that were necessary.

timeMillis - the time in milliseconds it took to merge the changes.

suspendMillis - the time in milliseconds the merge was suspended.

exclusive - whether the merge was holding an exclusive lock.

failedMerge

void failedMerge(int numRetries,
                 long timeMillis,
                 long suspendMillis,
                 boolean exclusive)

Reports to the collector that a merge failed.

Parameters:

numRetries - the number of retries that were done.

timeMillis - the time in milliseconds it took to attempt the merge.

suspendMillis - the time in milliseconds the merge was suspended.

exclusive - whether the merge was holding an exclusive lock.

doneWaitUntilHead

void doneWaitUntilHead(long waitMicros)

Reports to the collector that a commit finished waiting to become the head of the commit queue.

Parameters:

waitMicros - the time it waited in microseconds to be come the head of the queue.

doneMergeLockAcquired

void doneMergeLockAcquired(long timeMicros)

Reports to the collector that the commit acquired the merge lock in the given time.

Parameters:

timeMicros - the time in microseconds.

doneCommitHookProcessed

void doneCommitHookProcessed(long timeMicros)
