Oracle’s version of “actually, we’ve been doing MapReduce all along too”
In a recent blog post, Jean-Pierre Dijcks of Oracle makes the argument that Oracle has supported MapReduce all along, essentially because:
- You can do lots of procedural logic in the Oracle database, in a broad choice of languages, so in particular you can do Map steps.
- You can do lots of procedural logic in the Oracle database, in a broad choice of languages, so in particular you can do Reduce steps.
- Oracle offers a mechanism for parallelizing procedural logic.
Oracle doesn’t appear to have an explicit Map/Reduce programming interface, but I wouldn’t be surprised if Oracle Consulting cranked one out at some point to meet customer demand.
The post goes on to claim the usual in-database MapReduce benefit of avoiding the overhead of intermediate query result materialization. Presumably, then, Oracle’s quasi-MapReduce would also lack query fault-tolerance.
