> Store more metadata in HFiles
> -----------------------------
>
> Key: HBASE-6799
> URL: https://issues.apache.org/jira/browse/HBASE-6799
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Lars Hofhansl
>
> Current we store metadata in HFile:
> * the timerange of KVs
> * the earliest PUT ts
> * max sequence id
> * whether or not this file was created from a major compaction.
> I would like to brainstorm what extra data we need to store to make an HFile
> self describing. I.e. it could be backed up to somewhere with external tools
> (without invoking an HBase server) can gleam enough information from it to
> make use of the data inside. Ideally it would also be nice to be able to
> recreate .META. from a bunch of HFiles to standup a temporary HBase instance
> to process a bunch of HFiles.
> What I can think of:
> * min/max key
> * table
> * column family (or families to be future proof)
> * custom tags (set by a backup tools for example)
