Description

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.
