------------------------------------
Summary: Binarize trace level request logging along with debug
level text logging
Key: KAFKA-1590
URL: https://issues.apache.org/jira/browse/KAFKA-1590
Project: Kafka
Issue Type: Bug
Reporter: Guozhang Wang
Fix For: 0.9.0
With trace level logging, the request handling logs can grow very fast
depending on the client behavior (e.g. consumer with 0 maxWait and hence keep
sending fetch requests). Previously we have changed it to debug level which
only provides a summary of the requests, omitting request details. However this
does not work perfectly since summaries are not sufficient for
trouble-shooting, and turning on trace level upon issues will be too late.
The proposed solution here, is to default to debug level logging with trace
level logging printed as binary format at the same time. The generated binary
files can then be further compressed / rolled out. When needed, we will then
decompress / parse the trace logs into texts.
