--------------------------------

             Summary: Use different wals for different write workload table
                 Key: HBASE-22494
                 URL: https://issues.apache.org/jira/browse/HBASE-22494
             Project: HBase
          Issue Type: Improvement
            Reporter: binlijin


I observe some cluster have many wal files because there are different tables have different 
 write workloads, there share the same wal, and write heavy workloads table make wal files increasing fast, but write light workloads table make wal files archive slow...
There is a possible way is that make them in different namespace and use multiwal(namespace Strategies) to make them use different wals, but it need to design it at first before providing service.
