Summary: Add batching to HLogPerformanceEvaluation
Key: HBASE-10094
URL: https://issues.apache.org/jira/browse/HBASE-10094
Project: HBase
Issue Type: Sub-task
Reporter: stack
Assignee: Himanshu Vashishtha
As Himanshu points out in the the parent issue, HLogPE is using an unorthodox
API appending edits to the WAL; it is using an API that is meant for tests only
that does an append immediately followed by a sync call.
In normal deploy, WAL appends are done as a bunch of appends followed by a sync
on the tail of the transaction -- not a sync per append.
This issue is about changing HLogPE to use append and then sync. It also adds
an argument so you can specifying batching of a set of appends before the sync
is called. The latter lets HLogPE mimic multi puts that use the minibatch...
which appends, appends, appends.. and then syncs.
Assigning to Himanshu for review.
