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

 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!
