>                 Key: HBASE-22494
>                 URL: https://issues.apache.org/jira/browse/HBASE-22494
>             Project: HBase
>          Issue Type: Improvement
>          Components: wal
>            Reporter: binlijin
>            Priority: Major
>
> 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.
