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.

In scylla grafana board, this issue is seen with high number of foreground read tasks.



Thanks
Saurabh
