      Description

      My last email on the thread "Should we change the default value of hbase.regionserver.flushlogentries for 0.21?"

      Ok to make sure I get this right:

      • we enable deferred log flush by default
      • we set flushlogentries=1

      Also since 10 seconds is kind of a huge window I propose that:

      • we set optionalLogFlush=1000

      which is the MySQL default. We also have to update the wiki (there's
      already an entry on deferred log flush) by adding the configuration of
      flushlogentries.
