James Taylor commented on PHOENIX-3525:
---------------------------------------

[~samarthjain] - this is the JIRA we were discussing. Rather than using the 
timestamp at which the index was marked active, I'd lean toward adding a new 
INDEX_ENABLED_TIMESTAMP instead so that we can handle the case of keeping the 
index active.

> Cap automatic index rebuilding to inactive timestamp.

> For automatic rebuilding ,DISABLED_TIMESTAMP is lower bound but there is no 
> upper bound so we are going rebuild all the new writes written after 
> DISABLED_TIMESTAMP even though indexes updated properly. So we can introduce 
> an upper bound of time where we are going to start a rebuild thread so we can 
> limit the data to rebuild. In case If there are frequent writes then we can 
> increment the rebuild period exponentially
