[jira] [Comment Edited] (HBASE-7233) Serializing KeyValues
[ https://issues.apache.org/jira/browse/HBASE-7233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13573760#comment-13573760 ]

bq. I was thinking would just return no tags in v1 rather than unsupported?
Sure, easy.
Let's at least get the placeholders in. Both HBASE-7662 and HBASE-7663 would need efficiently stored and accessed tags in KVs, and [~enis] was also talking about using KV tags for holding metadata for grouping rows recently if I recall correctly. It would be even better if there was a "BasicCellEncoderV2" that could actually store and retrieve tags, at least in unit tests, even if not baked enough to actually use until a later release. Enough to prove the tag accessor methods workable. Something to build on.
