Can you slice up the "slows down" part a little more?
Are you saying you are getting 4500 u-sec write latency ?
Are you using secondary indexes?
What sort of read queries are slowing down?
What does the schema look like ?
If the simple checks like CPU, iostat and GC logging in the cassandra l
I have a 4 node cluster with lots JVM memory and lots of system memory that
slows down when I'm doing lots of writes.
Running DataStax charts I see my read and write latency rise from 50-100
u-secs to 1500-4500 u-secs. This is across a 12 hour data load during
which time the applied load is high
