-----------------------------------------
Resolution: Won't Fix
> Support coupled compactions with secondary index
> -------------------------------------------------
>
> Key: HBASE-13519
> URL: https://issues.apache.org/jira/browse/HBASE-13519
> Project: HBase
> Issue Type: New Feature
> Reporter: tristartom
> Priority: Major
>
> Hi,
> DELI (DEferred Lightweight Indexing) is our research prototype from Syracuse
> University with collaboration from Georgia Tech and IBM Research.
> In DELI, we propose that when supporting secondary index on HBase, the
> index-to-base-table sync-up should be coupled with compaction. The benefit of
> this is that online Put stays to be append-only and performance would be
> guaranteed.
> The code of DELI is shared in github:
> https://github.com/tristartom/nosql-indexing
> Details can be found in the following research paper published in CCGrid
> 2015: http://tristartom.github.io/docs/ccgrid15.pdf
> We are grateful for the HBase community, and any comments/suggestions are
> appreciated.
