The team behind RethinkDB has released the first version since it was taken under community governance. The main changes to this version are bug fixes and stability improvements, but it shows that the team is moving forward.
RethinkDB is an open source NoSQL JSON database designed for web apps. Its main differentiator is that you can tell it to continuously push updated query results to applications in real time, rather than having your app poll for changes.
The company who had developed RethinkDB launched a Windows version early in 2016, but by October last year had decided they could no longer continue commercial development. The database market is of course dominated by a few very big names, and while RethinkDB has some excellent attributes, it was fighting for space in a crowded market where the 'safe' choice was always going to be something else.
When the company behind RethinkDB shut down last year, it looked as though RethinkDB might disappear. Fortunately, a group of community members and former employees took it on as an open source software project. That effort culminated earlier this year when the group officially joined the Linux Foundation and re-licensed RethinkDB under the permissive ASLv2.
The changes to this release are mainly bug fixes and compatibility improvements. The new release has a webUI that works better with Chrome 49 and Edge. Regression is handled better, and the argument order in queries in the jobs table now shows correctly.
Writing about the new release on the RethinkDB blog, developer Ryan Paul said:
"Although development on RethinkDB never really halted, it took some time to spin up the infrastructure and processes that we needed to facilitate new releases. Now that we’re back in action, we’re looking forward to rolling out more regular updates."
Work is now underway on RethinkDB 2.4, the next major version, which will include support for table modifier functions. These let you provide an arbitrary ReQL expression for the database to execute on every write operation that affects a table’s contents.
Given our expectations of Xbox games, you might consider writing a game within a 13K limit, which is the challenge for the annual js13K competition far too restrictive. Its results are now out and prove that it is possible to produce a game that is fun to play.
