Happy day! Welcome to the second edition of ‘This Month in TiKV’, covering August 2019. (Yes we know it’s later than the first week of September, sorry!)

Migrating the TiKV Rust client from futures 0.1 to 0.3

I recently migrated a small/medium-sized crate from Futures 0.1 to 0.3. It was fairly easy, but there were some tricky bits and some things that were not well documented, so I think it is worth me writing up my experience. The crate I migrated is the Rust client for the TiKV database. It is about 5500 LoC and uses futures fairly heavily (because it communicates with TiKV using gRPC and the interface to that is async).

Hi! Welcome to the first ever edition of ‘This Month in TiKV’, covering July 2019.

We’re just getting started with the newsletter, and you should expect it to evolve as we go along.

TiKV 3.0 GA Release

July 17, 2019

Today we’re proud to announce the general availability of TiKV 3.0! Whether spanning hundreds of nodes or storing over a trillion key-value pairs, we’ve seen our users put TiKV to the test in serious, real-world, production scenarios. In 3.0, we’ve applied the lessons learned from these deployments to bring a host of new features that can better support users’ growing demands. Before release, TiKV 3.0 additionally underwent an official Jepsen test with TiDB.

Distributed Systems Training in Rust and Go

Brian Anderson, Senior Database Engineer for TiKV

June 20, 2019

On the TiKV team we love the Rust and Go programming languages. They are the languages in which we write most of our software, with TiKV in Rust, and its sister project, TiDB, in Go. They have empowered us to build these fast and reliable distributed systems from the ground up, and iterate on them quickly and confidently. These languages are the future of systems programming. Creating reliable distributed systems like TiKV demands a lot from contributors — they not only need to be experts in storage and distributed systems, but also to be comfortable expressing that knowledge in these modern languages.
