First time I heard about CouchDB was many years ago. I bought an O’Reilly book about it, even. At the time MongoDB was gaining a lot of traction, and I think because of that many people overlooked CouchDB.
I recently remembered CouchDB because I have some projects that could potentially benefit from replication between multiple machines. And in the case of my projects I think the database level would be an appropriate place to do replication. Hence CouchDB is an interesting proposition for my projects.
I installed CouchDB on my laptop for the first time in ages, and started inserting documents into it with a third party library for Rust. So far it is working nicely.
