stack commented on HBASE-5262: ------------------------------ @Mikhail Sounds good. We'd write to hbase because we can't have many writers write same file in hdfs? This system table would be a new one, not .META.? We'd fill it to the end of time or the TTL on the table would get rid of old records (that'd work). > 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. -- This message is automatically generated by JIRA.
