----------------------------------
Summary: Per-request tracing
Key: KAFKA-1440
URL: https://issues.apache.org/jira/browse/KAFKA-1440
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Todd Palino
Could we have a flag in requests (potentially in the header for all requests,
but at least for produce and fetch) that would enable tracing for that request.
Currently, if we want to debug an issue with a request, we need to turn on
trace level logging for the entire broker. If the client could ask for the
request to be traced, we could then log detailed information for just that
request.
Ideally, this would be available as a flag that can be enabled in the client
via JMX, so it could be done without needing to restart the client application.
