A Newsletter About Everything Redis

Issue #13
October 9th, 2014

Editor’s Note

Stories and News

Redis cluster, no longer vaporware. (13 minutes to read)

Today’s release of Redis v3.0RC1 with built-in clustering support is accompanied by @antirez‘s overview of the project’s history, the goals, current capabilities and the road ahead.

Redis Developers Day – The Redis Labs Writeup (13 minutes to read)

Last week we’ve attended the best and first ever Redis Developers Day – here’s a report of this unique experience.

A few urgent issues identified during the October 2014 dev meeting (13 minutes to read)

@antirez‘s closing tweet from the item above has been translated to issue #2045 in the Redis repository. Lots and lots of goodies in that one including: diskless replication, hybrid lists, Matt’s geocoding plugin and Lua command replication (as opposed to script replication).

But perhaps the most surprising item in that list, added only yesterday, is opt-in support for SSL. Besides overturning issue #71‘s much-debated WontFix status, having native SSL support means you won’t need to use stunnel anymore. Good thing that there are already several SSL-enabled client libraries for Redis 🙂 #SecuRedis

A Fresh Look at Rust (13 minutes to read)

After having recently completing a rewrite of his Redis client library, @mitsuhiko puts some of his Rust development experience into writing: “Rust is in your face with memory and data. It’s very much like C and C++. However unlike C and C++ it feels more like you’re programming with Python from the API point of view because of the type inference and because the API of the standard library was clearly written with programmer satisfaction in mind.”
