Structured event log for HBase for monitoring and auto-tuning performance
-------------------------------------------------------------------------

                 Key: HBASE-5262
                 URL: https://issues.apache.org/jira/browse/HBASE-5262
             Project: HBase
          Issue Type: Improvement
            Reporter: Mikhail Bautin


Creating this JIRA to open a discussion about a structured (machine-readable) log that will
record events such as compaction start/end times, compaction input/output files, their sizes,
the same for flushes, etc. This can be stored e.g. in a new system table in HBase itself.
The data from this log can then be analyzed and used to optimize compactions at run time,
or otherwise auto-tune HBase configuration to reduce the number of knobs the user has to configure.
