      Description

      There is a clear CPU drain and iterator creation when creating store scanners under high load. Splice was running a TPCC test of our database and we are seeing object creation and CPU waste on the boolean check....

      Code Snippet...

      if (store != null && ((HStore)store).getHRegion() != null
      && store.getStorefilesCount() > 1)

      { RegionServerServices rsService = ((HStore)store).getHRegion().getRegionServerServices(); if (rsService == null || !rsService.getConfiguration().getBoolean( STORESCANNER_PARALLEL_SEEK_ENABLE, false)) return; isParallelSeekEnabled = true; executor = rsService.getExecutorService(); }

      Will attach profile...
