Jim Witschey created CASSANDRA-11081:
----------------------------------------
Summary: Benchmark for & write recommendations for which SSTable
compressor to choose
Key: CASSANDRA-11081
URL: https://issues.apache.org/jira/browse/CASSANDRA-11081
Project: Cassandra
Issue Type: Task
Components: Documentation and Website
Reporter: Jim Witschey
Priority: Minor
This task was generated in breaking apart the initial test plan for
CASSANDRA-10995. [~slebresne] said doing this task would be useful, but out of
scope for that ticket, and perhaps not worth the effort right now.
It would be helpful to us and for users to know: what kinds of workloads should
use which SSTable compressor? Currently, I believe all we can do for users is
say "run your own benchmarks", but it would be good to have enough information
to say, e.g., "workloads with (property x) benefit from using LZ4".
Post-CASSANDRA-8099, there is less on-disk storage engine overhead that can be
compressed, so choice of compressor is probably more workload-sensitive than it
used to be, so the choice of using compression in the first place is less
obvious.
