The chattiness is mostly addressed with _bulk_get in CouchDB 2.0 - Pouch will automatically use it if the server supports it. Another option is to stick a HTTP/2 proxy in front of your CouchDB instance - the chatter to the db is ultima

There are a lot of use cases, particularly around multi-region/DC master-master replication, where CouchDB/Cloudant is a great fit. IBM also offers MongoDB, RethinkDB, Postgres as managed services and the MVCC/conflict model

I think there's a lot for you to like in 2.0. > The replication protocol, which supports multi-master, has changed little Basically true, though with many interoperating, independent datastores it's a tricky thing to evolve. 2.

possibly this has changed recently but I don't think medical records software is subject to the same standards as medical device software (in Europe, at least). It's important to remember that EMRs are there to support healthcare

For MongoDB lovers, PouchDB supports MongoDB-style querying via https://github.com/nolanlawson/pouchdb-find . MongoDB doesn't have the fundamental sync primitives that CouchDB has so I wouldn't expect a simila

That's fine for scaling reads - writes, not so much. The leader election in MongoDB has been problematic in the past ( https://aphyr.com/posts/284-call-me-maybe-mongodb ) but I think they have made recent moves to a

ES isn't really meant to be used as an operational datastore (although I appreciate some do use it that way). CouchDB provides strong durability and master-master replication. It's also very easy to sync changes from CouchDB ( htt

Although it's been a quiet few years, the project is on the up again. 2014 was a big year for CouchDB - CouchDB 2.0 developer preview was released (more on this in a sec) [1], IBM acquired Cloudant (and has made it available as on-prem

database-per-user is a common pattern with CouchDB. If you need to aggregate data across your users for reporting etc then you can use a server-side replication to create a "master" database which is only accessible to your intern

We (Cloudant) ran a Jepsen-style test against our clustered CouchDB implementation (similar to BigCouch). The write-up is at https://cloudant.com/blog/run-dmc-explains-network-partition... . The clustering layer is gett

shameless plug: Cloudant Geo ( https://cloudant.com/product/cloudant-features/geospatial/ ) uses a sharded R*-Tree for big geospatial data.

True - multi-master in CouchDB means that you can have two CouchDB instances (or, indeed, anything which speaks the CouchDB replication protocol - see http://www.replication.io/ ) which can be synced and, in the event of a n

One problem is that as a vendor, we have to work to the lowest common denominator. It's still generally a requirement that you support IE6, despite the department of health encouraging hospitals to upgrade, because they have legacy apps whe

As a vendor in the UK, we have been integrating the CUI for the last few years. The quality of the guidance is mixed - there is good evidence that having a "Patient Banner" in a consistent format prevents "right thing, wrong patient" proble

It is possible to work in an agile manner with the NHS but it is not easy. I have been working for a small company selling software into NHS hiospitals for 7 years now, and we generally take a collaborative approach with customers when deve
