Subject [jira] Commented: (HBASE-2396) Coprocessors: Server side dynamic scripting language execution
Date Tue, 14 Dec 2010 00:02:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12971091#action_12971091
] 

Andrew Purtell commented on HBASE-2396:
---------------------------------------

As discussed at the hackathon, the first cut of this should be an Endpoint that accepts code
to execute as a string and sends back results. As Result? 

Later we can optimize through a facility for registering stored scripts and referencing them
by name in RPCs.

> There are a lot of use cases where users want to perform some simple operations on the
region server. For example, a row may represent a Set and users want append/search/remove
style operations within the row without having to perform the work on the client side. One
possible solution is to embed a small language something like PL/SQL (not necessarily in syntax)
which restricts users to a safe set of operations.
