Lars Hofhansl updated HBASE-13159:
----------------------------------
Summary: Consider RangeReferenceFiles with transformations (was: Consider
RangeReferences with transformations)
> Consider RangeReferenceFiles with transformations
> -------------------------------------------------
>
> Key: HBASE-13159
> URL: https://issues.apache.org/jira/browse/HBASE-13159
> Project: HBase
> Issue Type: Brainstorming
> Reporter: Lars Hofhansl
>
> Currently we have References used by HalfStoreReaders and HFileLinks.
> For various use case we have here we have need for a RangeReferences with
> simple transformation of the keys.
> That would allow us to map HFiles between region or even tables without
> copying any data.
> We can probably combine HalfStores, HFileLinks, and RangeReferences into a
> single concept:
> * RangeReference = arbitrary start and stop row, arbitrary key transformation
> * HFileLink = start and stop keys set to the linked file's start/stop key,
> transformation = identity
> * (HalfStore) References = start/stop key set according to top or bottom
> reference, transformation = identity
> Note this is a *brainstorming* issue. :)
> (Could start with just references with arbitrary start/stop keys, and do
> transformations later)
