Subject [jira] [Commented] (HBASE-2038) Coprocessors: Region level indexing
Date Fri, 06 Jan 2012 03:58:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2038?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13181077#comment-13181077

Lars Hofhansl commented on HBASE-2038:
--------------------------------------

I see. So if I wanted to do a Get and all I have is the value of an indexed column, I have
to ask all regions, correct? (Because there is no way to identify the region with the column
value ahead of time)

> 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.
