Introduction to the fast new UnQLite Python Bindings

About a year ago, I blogged about some Python bindings I wrote for the embedded NoSQL document store UnQLite. One year later I'm happy to announce that I've rewritten the library using Cython and operations are, in most cases, an order of magnitude faster.

This was my first real attempt at using Cython and the experience was just the right mix of challenging and rewarding. I bought the O'Reilly Cython Book which came in super handy, so if you're interested in getting started with Cython I recommend picking up a copy.

In this post I'll quickly touch on the features of UnQLite, then show you how to use the Python bindings. When you're done reading you should hopefully be ready to use UnQLite in your next Python project.

Python bindings for UnQLite, an embedded NoSQL database/JSON document store

Note, Aug 2015: I've rewritten the UnQLite Python bindings using Cython, and they are much faster. Here is a blog post announcing the update.

Original post:

I'm happy to write that I've just released some python bindings for UnQLite, an embedded NoSQL database and JSON document store. UnQLite might be characterized as the SQLite of NoSQL databases, though it's JSON document-store and Jx9 scripting language make it a pretty unique offering. UnQLite is created by Symisc Systems, who are also responsible for Vedis, an embedded Redis-like database (I also wrote some python bindings for vedis). Here is a quick overview of some of UnQLite's features, as described on the project homepage:

  • Embedded, zero-config database
  • Transactional (ACID)
  • Single file or in-memory database
  • Key/value store
  • Cursor support and linear record traversal
  • JSON document store
  • Thread-safe
  • Terabyte-sized databases

In the rest of this post I will show some basic usage of the unqlite-python library. If you'd like to follow along, you can use pip to install unqlite:

pip install unqlite

You can find the project source code hosted on GitHub and the documentation is available on readthedocs.
