---------------------------------------
[~jisaac], what we chatted about.
> Consider "programmatic" HFiles
> ------------------------------
>
> Key: HBASE-22385
> URL: https://issues.apache.org/jira/browse/HBASE-22385
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Lars Hofhansl
> Priority: Major
>
> For various use case (among other there is mass deletes) it would be great if
> HBase had a mechanism for programmatic HFiles. I.e. HFiles (with HFileScanner
> and Reader) that produce KeyValue just like any other old HFile, but the key
> values produced are generated or produced by some other means rather than
> being physically read from some storage medium.
> In fact this could be a generalization for the various HFiles we have:
> (Normal) HFiles, HFileLinks, HalfStoreFiles, etc.
> A simple way could be to allow for storing a classname into the HFile. Upon
> reading the HFile HBase would instantiate an instance of that class and that
> instance is responsible for all further interaction with that HFile. For
> normal HFiles it would just be the normal HFileReader.
> (Remember this is Brainstorming)
