----------------------------------------
Summary: Proposal to change concurrent_* and
native_transport_max_threads defaults
Key: CASSANDRA-12028
URL: https://issues.apache.org/jira/browse/CASSANDRA-12028
Project: Cassandra
Issue Type: Improvement
Reporter: Robert Stupp
Priority: Minor
The current recommendations in c.yaml regarding
{{concurrent_reads/writes/counter_writes/materialized_view_writes}} and
{{native_transport_max_threads}} feel oversized.
While working on some load/stress tests, reducing these to the number of CPUs
and also lowering {{native_transport_max_threads}} to 2xCPUs had no influence
to the actual performance but reduced the risk of allocating too many threads
when a node ran into a longer GC and requests against that node piled up.
