Jay Ghiya commented on BEAM-12844:
----------------------------------

Hi [~kenn] - Couple of things. So we use beam heavily as part of our batch 
pipelines. One of the biggest shortcoming of apache beam cassandra IO is that 
it does not provide any api for doing concurrent queries based on primary keys. 
For Example: We have 1000 keys. So instead of doing a full scan across 
scylla/cassandra system table to find out token ranges, we got atleast 3x low 
latency while using our own modified version of cassandra IO.

So Looks like both of them should be provided by cassandra IO. 
* When User has primary keys
* When User does not have primary keys

We were planning to merge this ssl change in that modified cassandra io and 
then make it open source. We already discussed this with scylla team and they 
see a definite value in the modified version. So would want your 
validation/review/support on making that cassandra IO merge with existing one. 
Will that be feasible?

> Not Able to use cassandra Io with ssl enabled cosmos db or cassandra as 
> cassandra IO does not expose cluster builder options. This looks like a basic 
> feature set. It would be great to resolve this as early as possible to avoid 
> organizations rejecting it due to missing ssl feature.
