Subject [jira] [Commented] (ACCUMULO-164) Add support for wildcards/regexes in locality group setting.
Date Thu, 07 Feb 2013 17:37:12 GMT


Keith Turner commented on ACCUMULO-164:

bq. We've already extended the original idea behind locality groups, by allowing users to
specify more than one column family for a locality group.

Accumulo did not extend it.  The Big Table paper described a locality group as a set of column
families.   In Hbase each col fam is a locality group.  Accumulo may differ from Big Table
in that it allows user to change what col fams are in a locality group, not sure about this.
 It also differs by having a default locality group.

> 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.
