It’s been quiet on this site for a couple of months, and that’s because as usual we’re all heads-down working. So many things to do, so many things. Sometimes however, one has to take a step back and look around, see what’s happening, see what’s around the corner, and see what others are doing.
A few years ago, all of us attended MongoDB “days” in London which were interesting, niche-ish geek-fests. That has really changed now. MongoDB is over a decade old, and at the MongoDB Europe conference today, they officially announced version 3.6, and its impressive feature-set.
Our intrepid loon Ben attended said conference which was well-organised, well-attended, and pretty well-populated with useful content. Particular sessions of note included those on the forthcoming developer-focused product MongoDB Stitch, along with MongoDB Atlas which has been in beta for some time. These satellite offerings look great (oh my: query-able back-ups in Atlas!), but what of the core product?
Well, version 3.6 of MongoDB offers a number of intriguing features, which can be summarised as follows:
- Change streams: invoked with a simple
coll.watch()these are Observers for MongoDB. Fab! - “Retryable” writes in the event of failures.
- Oodles of document updates including hugely increased “expressibility” in queries, aggregations, pipelining, array processing and updating. These look to be very powerful, and I think Matt will be cock-a-hoop with them.
- R driver to support advanced analytics and business intelligence.
- Support for JSON schema.
- Tunable consistency: customise your app’s balance between read-write consistency needs and overall availability.
You can read more about 3.6 and the future of MongoDB on the official web site.
