Alex Baranau commented on HBASE-2038:
-------------------------------------
Re comparing this solution to others:
ITHBase: you can find very good comparison in HBASE-2037 description
Lily: apart from different implementation base (Lily uses Lucene while IHBase
currently not) IHBase is more like "internal" feature added HBase, not a
separate/additional tool/system. I.e. provides in-house support for secondary
indexing.
Culvert: haven't looked into the internals yet (definitely will), but it looks
like this may be smth similar. Not sure
+1 for doing evaluating and learn from other's experience use-cases to make
"native support" (IHBase-2) better.
> Coprocessors: Region level indexing
> -----------------------------------

> Key: HBASE-2038
> URL: https://issues.apache.org/jira/browse/HBASE-2038
> Project: HBase
> Issue Type: New Feature
> Components: coprocessors
> Reporter: Andrew Purtell
> Priority: Minor
>
> HBASE-2037 is a good candidate to be done as coprocessor. It also serve as a
> good goalpost for coprocessor environment design -- there should be enough of
> it so region level indexing can be reimplemented as a coprocessor without any
> loss of functionality.
