Two things happened today for me to ask this question and am not offering any serious answer, yet !
- First I had some quick chat with folks at MongoDB and as a result got me thinking about the MapReduce in Mongo and where could it go. MongoDB also has the new declarative aggregation framework.
- My thesis is that, while now the MongoDB aggregation framework is JSON semantics+$ keywords, it could look a lot like a functional programming language – with high-order declarative functions like map/reduce, discriminated unions (like F#) and currying.
- And later in the day I read Edd’s blog “5 Big Data Predictions”, also in Forbes. (While both are the same blog, there might ne interesting comments in each)
- Lots of interesting observations from Edd. He is predicting better programming language support, but may be we are looking at it the wrong way – what we need is a better stored procedure support in the data layer. It also could the next point Edd was talking about-Streaming data processing ! Where best could we have that feature than at the data layer ?
- Would we be able to write a social science data platform using the MongoDB aggregators ? Would MongoDB mapReduce fit the bill now ? If not, what would it take to make it so ?
- There are two obvious paths – connector to an application artifact for example Hadoop connector or embed the map/reduce in the data layer. Both have their advantages and disadvantages. With the connector the mapReduce can scale orthogonally, but with the embedded feature, one can achieve real-time processing (within limits). May be this is the time for an application data store !
- Would the datastores like MongoDB gain features like the Twitter Storm, Real-Time map reduce, hierarchical iterative functional aggregators and so forth ?
- GreenPlum’s Chorus is interesting – Can NOSQL datastores gain some of the relevant capabilities that Chorus has?
Finally, the beginning as the end,
- Is hadoop the new stored procedure or would the new stored procedures look like Hadoop ?
- Is Data and Application becoming inseparable at scale ?
- What says thee?
