Subject [jira] Commented: (HBASE-669) MultiRegion transactions with Optimistic Concurrency Control
Date Tue, 12 Aug 2008 21:11:44 GMT

stack commented on HBASE-669:
-----------------------------

I tried to apply last patch Clint. Fails in HTable.  I'd like to commit this.  It has a bunch
of unit tests so its at least basically working.  Blocker is lack of package documentation.
 Please add a package.html (see thrift package for example) or a package-info.java (e.g. mapred
package) that explains what this is all about with pointer to the OCC paper and a basic howto
on what configuration is needed to make a transactional hbase float.  Thanks Clint.

> We have a need for ACID transactions across tables. This issue is about adding transactions
which span multiple regions.  We do not envision many competing writes, and will be read-dominated
in general. This makes Optimistic Concurrency Control (OCC) seem like the way to go.
