Andrew Purtell updated HBASE-9352:
----------------------------------
Affects Version/s: 0.98.0
> Refactor HFile block encoding
> -----------------------------
>
> Key: HBASE-9352
> URL: https://issues.apache.org/jira/browse/HBASE-9352
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.98.0
> Reporter: Andrew Purtell
>
> The set of block encoders available for processing HFiles is fixed at compile
> time. Rather than hardcode the set of available encoders in an enum, consider
> a registry and a couple of APIs for adding additional encoders at runtime.
> Modify HFile (V3) metadata to specify encoders by string or classname.
> Consider a stackable encoding API, so coprocessors can watch, change, or
> override block coding in upcalls.
> Block encoders are tightly bound to the particulars of HFile version
> internals. It would be good if some of that can go away.
> Could also consider dynamic loading of encoder implementations.
