-------------------------------------
Summary: Enable HBase to log the entire latency profile for HDFS packets resulting in slow writes.
Key: HBASE-8744
URL: https://issues.apache.org/jira/browse/HBASE-8744
Project: HBase
Issue Type: Improvement
Reporter: Pritam Damania
Priority: Minor
When we see WAL outliers in HBase, at times it is not clear which component in the whole stack is slow. At facebook we are implementing per request profiling which passes profiling information throughout the entire stack. This information can be used to determine the outliers in HBase.
