--------------------------------------
Summary: Add EXCLUDE_NAMESPACE and EXCLUDE_TABLECFS support to
replication peer config
Key: HBASE-19492
URL: https://issues.apache.org/jira/browse/HBASE-19492
Project: HBase
Issue Type: Improvement
Reporter: Guanghao Zhang
Assignee: Guanghao Zhang
This is a follow-up issue after HBASE-16868. Copied the comments in HBASE-16868.
This replicate_all flag is useful to avoid misuse of replication peer config.
And on our cluster we have more config: EXCLUDE_NAMESPACE and EXCLUDE_TABLECFS
for replication peer. Let me tell more about our use case. We have two online
serve cluster and one offline cluster for MR/Spark job. For online cluster, all
tables will replicate to each other. And not all tables will replicate to
offline cluster, because not all tables need OLAP job. We have hundreds of
tables and if only one table don't need replicate to offline cluster, then you
will config a lot of tables in replication peer config. So we add a new config
option is EXCLUDE_TABLECFS. Then you only need config one table (which don't
need replicate) in EXCLUDE_TABLECFS.
Then when the replicate_all flag is false, you can config NAMESPACE or TABLECFS
means which namespace/tables need replicate to peer cluster. When replicate_all
flag is true, you can config EXCLUDE_NAMESPACE or EXCLUDE_TABLECFS means which
namespace/tables can't replicate to peer cluster.
