Subject [jira] [Commented] (HBASE-2038) Coprocessors: Region level indexing
Date Fri, 06 Jan 2012 03:50:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13181074#comment-13181074

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.

> 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.
