Henrik Ingo: Drizzle JSON HTTP interface now with key-value support
The thing I really like with open source is the feeling you get when people just show up from nowhere and do great things to some code you originally wrote. Thanks to this miracle, I can now also present to you version 0.2 of the Drizzle JSON HTTP support, featuring a "pure JSON key-value API" in addition to the original "SQL over HTTP" API in 0.1 version. Let's recap what happened:
- At Drizzle Day 2011, I proposed that Drizzle should make available a JSON NoSQL interface. Stewart took the bait and published json_server 0.1 a week later. This API still uses SQL, it's just that the client protocol is HTTP and JSON, into which the SQL is embedded. So I suppose it's not as sexy as real NoSQL, but pretty cool nevertheless.
- At the end of last Summer I had a lot of dead time so I started playing with Stewart's code to see what I could do. I added a new API in addition to Stewart's SQL-over-HTTP API that supports key-value operations in pure JSON, similar to what you see in CouchDB, MongoDB or Metabase. I got it working quite well, however, I never implemented a DELETE command, because I then drifted off to more important tasks, such as revamping the Drizzle version numbering and bringing DEB and RPM packaging up to date.
- Last week a new but very promising Drizzle hacker called Mohit came by, looking for things he could do. He had already fixed a simple low-hanging-bug and wanted something more. Since he was interested in the JSON API, I asked if he wants to finish the missing piece. With my helpful advice of "there is no documentation but if you look at the demo GUI you'll probably figure it out, then just look at the code for POST and implement DELETE instead". I was afraid that wasn't really helpful, but I was busy that day. No problem, the next day Mohit had pushed working DELETE implementation. The day after that he implemented the final missing piece, a CREATE TABLE functionality. I was both impressed and excited.
