Titan-Cassadra: backend exception when searching for node #1378
Comments

I'm searching for nodes in a graph with
~21M
nodes (single machine, 24 cores, 120GB RAM), the query is the followingthere are no indexes involved.
I get the following exception
but with no stack trace or any other info.
I do not find anything in the Cassandra log either.
How do I investigate this?
Should I tune some configuration parameter?
