> Minor improvements in Cassandra shutdown and startup logs
> ---------------------------------------------------------
>
> Key: CASSANDRA-19818
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19818
> Project: Cassandra
> Issue Type: Improvement
> Components: Local/Startup and Shutdown
> Reporter: Dmitry Konstantinov
> Assignee: Dmitry Konstantinov
> Priority: Normal
> Fix For: 5.0.x, 5.x
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> To improve a DBA experience the following log messages would be nice to
> add/adjust:
> * on shutdown: an explicit message at the end of Cassandra shutdown
> * on startup:
> ** print the time spent to load prepared statements
> ** print the time spent to load repair session information and the number of
> loaded session records
> ** print the time spent to apply commit log
> It would help with assessment of possible delays in startup/shutdown of
> Cassandra. For example, recently I observed a delay in Cassandra startup and
> from logs it was not clear was it caused by loading of prepared statements or
> repair service init.
