Readme
Embedded persistent database for Node.js, with no dependency (except npm modules of course). The API is the same as MongoDB.
I needed to store data from another project (Braindead CI). I needed the datastore to be standalone (i.e. no dependency except other Node modules) so that people can install the software using a simple npm install. I couldn't find one without bugs and a clean API so I made this one.
It will be published as an npm module once it is finished. To launch tests: npm test.
It is pretty fast on the kind of datasets it was designed for (10,000 documents or less). On my machine (3 years old, no SSD), with a collection with 10,000 documents:
Read, update and deletion times are pretty much non impacted by the number of concerned documents. Inserts, updates and deletions are non-blocking. Read will be soon, too (but they are so fast it is not so important anyway).
You can run the simple benchmarks I use by executing the scripts in the benchmarks folder. They all take an optional parameter which is the size of the dataset to use (default is 10,000).
For now, a copy of the whole database is kept in memory. For the kind of datasets expected this should not be too much (max 20MB) but I am planning on stopping using that method to free RAM and make it completely asynchronous.
It's a subset of MongoDB's API.
