[jira] [Commented] (HBASE-8457) add support for custom entries to
PB WAL
[ https://issues.apache.org/jira/browse/HBASE-8457?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13644899#comment-13644899 ]
Enis Soztutar commented on HBASE-8457:
--------------------------------------
One option, we discussed at HBASE-2231 was to add a KeyValue.Type specific for this. But this is fundamentally different than adding the type to the wal edit and not clear whether it will be better. Adding a type to waledit seems more appealing.

> Right now custom records are written by using fake KVs. With protobuf WAL, maybe we can use PB.
> I took a stab at it in HBASE-7413, but the changes will be large on top of that change, including probably merging HLogKey and WALEdit refactoring, to not add another entity for custom message. So I am going to preserve the fake-KV-based approach in HBASE-7413 and file this JIRA.
