----------------------------------
Change Category: Performance
Complexity: Normal
Component/s: Observability/Logging
Status: Open (was: Triage Needed)
> Optimize logging with lazy log parameter evaluation
> ---------------------------------------------------
>
> Key: CASSANDRA-15764
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15764
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability/Logging
> Reporter: Yifan Cai
> Assignee: Yifan Cai
> Priority: Normal
>
> Multiple logging statements in the source evaluate methods and use the return
> values as log parameter.
> It does no harm when the log level permits for the statement.
> However, for the logs that are permitted, the evaluation is a wastes of CPU.
> The log parameters are not needed, but still being evaluated!
> For such cases, lazy evaluation (by leveraging lambda) can be introduced to
> skip competing the string parameter.
