-------------------------------------------
Summary: htraced: avoid serializing spans to json unless TRACE
logging is enabled
Key: HTRACE-297
URL: https://issues.apache.org/jira/browse/HTRACE-297
Project: HTrace
Issue Type: Bug
Components: htraced
Affects Versions: 4.0
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
We have been unconditionally serializing spans to JSON, but only logging them
when TRACE logging is enabled. Profiling has revealed that this is a CPU
bottleneck. Let's put "if" statement guards around the log messages to avoid
doing this serialization unless it is really useful.
