> Key: HBASE-14456
> URL: https://issues.apache.org/jira/browse/HBASE-14456
> Project: HBase
> Issue Type: New Feature
> Affects Versions: 2.0.0, 1.3.0
> Reporter: Yu Li
> Assignee: Yu Li
> Fix For: 2.0.0, 1.3.0
>
> Attachments: HBASE-14456.branch-1.patch,

>
> In HBASE-5699 we introduced multiple wal, and after some succeeding works we
> now have two main kinds of wal providers: DefaultWALProvider and
> RegionGroupingProvider, while DefaultWALProvider supplies a _single_ wal per
> regionserver, RegionGroupingProvider supplies _multiple_ wals according to
> the RegionGroupingStrategy it's using.
> Now there're two kinds of RegionGroupingStrategy: _identity_ and _bounded_,
> in which "identity" only for testing (trial) purpose and "bounded" for
> randomly assigning region writes to bounded number of wals. Although the
> "bounded" strategy is good enough for IO leverage, we may still want a more
> "designed" way to distribute the region writes, like having one wal group per
> business.
> Since we already have namespace for multi-tenancy, it would be good to have
> namespace-based grouping strategy, and this is exactly what this JIRA is for.
> There might be more benefits if we have namespace-based wal group, like only
> replicating data for the namespace in need w/o filtering anything useless, or
> only force region flush for the heavy loaded namespace, etc. although we
> won't include all these in this single JIRA.
