I think more information is needed before this question can be answered. In many cases you manage the indexes by yourself. If that breaks, then you have a consistency problem or a bug in your own code. Consistency is tunable (trade off with performance and availability) and bugs can be fixed.  In any case, if you can shed a bit light on the use case, then it would be easier to answer your question.

Subject: Indexes Fragmentation
To: user@cassandra.apache.org

Hi all:

A client on a RDBMS faces quick index fragmentations, statistics become inaccurate. Many within 4 hours (fast updates + writes, but mostly updates).

I am looking into replacing the RDBMS with Cassandra.

Will I face the same issue with indexes with Cassandra?

Thank you!
