We get periodic bulk load (twice a month) in form of delimited data files.
We get about 10K files with average size of 50 MB. Each record is a row in
Cassandra table.
What is the best way to ingest data into cassandra in fastest possible way?
Thank you,

For writes it's negligible. For reads it makes a significant difference for
high tps and low latency workload. You would see up to 3x higher cpu with LZ4
vs no compression. It would be different for different h/w configurations.

Toppartions provide the most active partitions.
I am trying to do same thing. I was able to narrow down the largest partition
by looking at warning in system.log.
Given that I have the key, how to see the entire data for that key?
Thanks,

If you are using CMS garbage collector then you still have to set the
HEAP_NEWSIZE. With G1GC (new recommended GC) there is no concept of New or
Older generation.
