Hi.

I have a table with about 300k rows in it, and am doing a query that returns 
about 800 results.

select * from fc.co WHERE thread_key = 'fastcompany:3000619';

The read latencies seem really high (upwards of 500ms)? Or is this expected? Is 
this bad schema, or…? What's the best way to trace the bottleneck, besides this 
tracing query:

Or, how would you interpret that?

I'm not sure that row caches are being used, despite them being turned on in 
the cassandra.yaml file.

I'm using a 3 node cluster on amazon, using datastax community edition, 
cassandra 2.0.1, in the same EC2 availability zone. 

Many thanks,
@Mankins
