> Introduce a new WALProvider to generate WAL files consumed by Replication
> -------------------------------------------------------------------------

> Key: HBASE-29027
> URL: https://issues.apache.org/jira/browse/HBASE-29027
> Project: HBase
> Issue Type: Improvement
> Components: Replication, wal
> Reporter: Yutong Xiao
> Assignee: Yutong Xiao
> Priority: Major
> Labels: pull-request-available
>
> Under our current Replication implementation, all WAL files will be consumed
> and the data will be filtered by a table attribute
> REPLICATION_SCOPE_GLOBAL
>
> We are using 2.4.11 version in our production env. And we have a small group
> table to use the replication to do CDC, however with the growth of the number
> of other non-replicated tables, we met the log queue accumulation issue and
> the data lag grew to hours level.
>
> To solve the issue we write the tables, which has CF marked the
> replication_scope to global, to separated WAL files and let the replication
> only consume those files. The feature solved our problems and push it to the
> community.
