Subject [jira] [Commented] (HBASE-4879) Add Constraint support to shell
Date Mon, 28 Nov 2011 20:11:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158708#comment-13158708
] 

Jesse Yates commented on HBASE-4879:
------------------------------------

As a follow-on ticket to 4605, this means adding the support for altering a table more easily.
Specifically, this means doing something like:

{code}
alter("table").addCoprocessor(…)
alter("table").addColumnFamily(…)
…
{code}

and then for constraints, something like:

{code}
alter("table").addConstraint(…)
alter("table").enableConstraints
…
{code}

with those methods being added dynamically by a 'constraint module' in the jruby code. This
would also serve as an example for how further shell extension can be done in a modular manner.

This ticket may also become a more major revamp for the how the shell works, e.g. dropping
into a table context, etc as described in the discussion.
