RE: [EXTERNAL] Re: Null values in sasi indexed column

[Durity, Sean R]

I would consider building a lookup table instead. Something like:
Create table new_lookup (
   new-lookup-partition text,
   existing-key text
   PRIMARY KEY (new-lookup-partition)
)

For me, these are easier to understand and reason through for Cassandra 
performance and availability. I would use this approach for up to 3 or 4 
different lookup patterns. If it got to be more than that, I would be using DSE 
Search/SOLR.

Just be warned, I have seen teams asking for these kind of options just because 
they are guessing the access patterns they want. If they cannot identify their 
access patterns, I encourage them to use other technologies. Otherwise the pain 
will be great.

Rahul, in my opinion SASI is an experimental feature and isn't ready for 
primetime yet. It has some advantages over secondary indexes but if it were me, 
I'd stick with native secondary indexes. But test, test and test so you can 
make an informed decision on what works for your use case. Cheers!
