Hi Michael,
Thanks for putting very clever information " Users of MVs *must* determine for
themselves, through
thorough testing and understanding, if they wish to use them." And this
concluded that if there is any issue occur in future then only solution is to
rebuild the MVs since Cassandra does not able to make consistent synch well.
Also, we practically using the 10+ MVs and as of now, we have not faced any
issue, so my question to all community member, does anyone face any critical
issues ? so we need to start migration from MVs to manual query base table ?
Also, I can understand now, it's experimental and not ready for production, so
if possible, please ignore it only right ?
Thanks
Pankaj
