Brandon Williams created CASSANDRA-9364:
-------------------------------------------
Summary: Add a warning when a high setting for rpc_max_threads is
specified for HSHA
Key: CASSANDRA-9364
URL: https://issues.apache.org/jira/browse/CASSANDRA-9364
Project: Cassandra
Issue Type: Bug
Reporter: Brandon Williams
Fix For: 2.0.15
In CASSANDRA-7594 we allowed configuring this. The problem is this was ignored
for HSHA previously, so some people go through this scenario:
1. start with sync and 4000 threads
2. switch to HSHA, pre-7594
3. upgrade to a version after 7594, without changing this setting
4. experience awful performance due to insane thread contention
