Examples of BatchUpdate

org.apache.hadoop.hbase.io.BatchUpdate
A Writable object that contains a series of BatchOperations There is one BatchUpdate object per server, so a series of batch operations can result in multiple BatchUpdate objects if the batch contains rows that are served by multiple region servers.

      // 3. Insert into meta
          
      HRegionInfo info = region.getRegionInfo();
      Text regionName = region.getRegionName();
      BatchUpdate b = new BatchUpdate(rand.nextLong());
      long lockid = b.startUpdate(regionName);

      // 4. Close the new region to flush it to disk.  Close its log file too.
      
      region.close();
