noam bulvik commented on PHOENIX-4265:
--------------------------------------

in 4.12 if we use local index is the limitation on multiple indexes still exists ?

> FYI, due to the inability to keep an index in sync when there's a ROW_TIMESTAMP column,
as of 4.12 we're disallowing the creation of mutable secondary indexes when a table has a
ROW_TIMESTAMP column. Usually, since the timestamp is part of the row key, the data table
can be declared IMMUTABLE. In this case, the index would still be allowed.
