stack commented on HBASE-13393:
-------------------------------

We are still doing volatile boolean read on each update to memstore. In 90+% of 
cases, tags are not used? What if a table or column family config to say 'use 
tags'?

> Add facility to disable tags after parent goes in

> We used to specify 'no tags' by choosing to write files that were version 2.  
> After parent goes in, make it so can ask a v3 file not to write tags.
