Subject [jira] [Commented] (ACCUMULO-2336) support user-defined table metadata
Date Thu, 06 Feb 2014 23:33:26 GMT

John Vines commented on ACCUMULO-2336:
--------------------------------------

Sounds like a good use of a general purpose blob, possibly a description? The question is
size. If it's just a few tidbits, this is great for ZK. But it could blow up which would make
it better in a file in HDFS I think.

> An Accumulo table can have all sorts of external information that applications use to
interact with the table. One example is schema definition. Another might be information about
what data or data sources have been loaded into the table. It would be nice to encapsulate
all of this information together with the table's data for easier management, particularly
when cloning tables or discovering tables that are shared across applications (multi-tenancy).
> How can we support generic table metadata properties so that users can innovate independently?
These could be accessible via the table properties, or this could be a separate set of public
API methods if appropriate.
