> 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.
