Subject Re: [External] Re: Cassandra ad hoc search options

Hi
We used lucene stratio plugin with C*3.0.3

Helped to solve a lot of some read patterns. Served well for prefix.
But created problems as repairs failed repeatedly.
We might have used it sub optimally, not sure.

Later, we had to do away with it, and tried to serve most of the read
patterns with materialised views. (currently C*3.0.9)

Currently, for adhoc querries, we use spark or full scan.

Regards,
