stack commented on HBASE-22148:
-------------------------------

Whats a mutable index [~tdsilva]? How does the CP work? It takes current edits 
timestamp and uses that when it writes the index Cell? The Cell in the index 
table is a newly created Cell or you are reading back an existing Cell and 
doing an update on it? Thanks. Detail will help.

> Provide an alternative to CellUtil.setTimestamp

> {{CellUtil.setTimestamp}} has been deprecated in 2.0 and is marked for 
> removal in 3.0. Phoenix currently uses this api to set the timestamp of cells 
> in its indexing coprocessor for tables that have mutable indexes. We can't 
> use the CellBuilder api since this involves creating a copy of the cell which 
> will be expensive.
