Hi All, We are currently working on making Greenplum Large Objects better and awesome.
We were thinking of seeing if MADLib can benefit from Large Objects and use them in a manner which is helpful. MADLib can see if Large Objects can be used as intermediate objects for intermediate states that are large. Large Objects API can be seen http://www.postgresql.org/docs/9.2/static/largeobjects.html Large Objects will eventually scale out in Greenplum. They will be distributed across cluster and queries will be performant. Regards, Atri
