Hi all

We are using janusgraph at zeotap at humongous scale (~70B V and 50B E) backed by scylla.

Right now I am facing an issue in janusgraph_ids table, wherein there are large partitions created in the scylla DB, and this is leading to huge read performance issues. The queries hitting janusgraph_ids table are range queries and with large partitions, the reads are becoming super slow.  

I would like to know if anyone else has observed similar issue, is there a set of configurations that need to be checked or something else you would suggest.

Thanks
Saurabh
