Subject [jira] [Commented] (ACCUMULO-164) Add support for wildcards/regexes in locality group setting.
Date Mon, 04 Feb 2013 19:38:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13570560#comment-13570560

Josh Elser commented on ACCUMULO-164:
-------------------------------------

I'd like to rekindle discussion on this subject. I think supporting prefix-only definition
simplifies the difficulty in the configuration aspects; however, this might still be complicated
to do inside of RFile. There are arguments that can be made both for and against the feature.

*Against*: Many times requiring a prefix in the colfam implies that there is a table structure
change which could replace the necessity for this feature
*For*: Time to the millisecond in the colfam, and the user wants all colfams before the year
2000 stored in one locality group.

I'd like to restart the discussion to see if this might be something we want to tackle in
1.6.

> We should look into adding the ability to specify locality group columns as either wildcarding
or regexes. I'm unsure of the feasibility of this, hence the lack of fix date.
