Pavel Yaskevich commented on CASSANDRA-10661:
---------------------------------------------

[~doanduyhai] 

Regarding CONTAINS mode - it's more expensive to build since it has to extract 
the suffixes (which is exactly what search people are doing) which makes it as 
expensive to query as PREFIX columns. Regarding sorting - this is currently not 
a priority since it would require extensive changes to Cassandra interfaces to 
support that, MAX_ROWS currently is the same restriction per result page as in 
CQL3.

> We have recently released new secondary index engine 
> (https://github.com/xedin/sasi) build using SecondaryIndex API, there are 
> still couple of things to work out regarding 3.x since it's currently 
> targeted on 2.0 released. I want to make this an umbrella issue to all of the 
> things related to integration of SASI, which are also tracked in 
> [sasi_issues|https://github.com/xedin/sasi/issues], into mainline Cassandra 
> 3.x release.
