rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.5.0 is out. This release supports important control of foreign key constraints, in the underlying SQLite database. You can download the release from GitHub.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.4.1 is out. This release includes some minor fixes as well as source code improvements (linting). You can download the release from GitHub.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.4.0 is out, which includes a minor change to the HTTP responses. You can download the release from GitHub.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.3.0 has been released and includes new functionality to control the Raft consensus subsystem, along with improvements to the CLI. You can download the release from GitHub.
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.2.1 has been released and includes new functionality for cluster management, along with new documentation on running clusters. v3.2.0 also includes some bug fixes. You can download the…
rqlite is an open-source distributed relational database, which uses SQLite as its storage engine. rqlite is written in Go and uses Raft to achieve consensus across a set of SQLite databases. It gracefully handles leader election, and can tolerate machine…
rqlite is an open-source distributed relational database, with SQLite as its storage engine. v3.0.1 has been released and it is a significant upgrade relative to the 2.0 series. The 3.0 series allows more sophisticated clusters to be built and simplifies rqlite…
Thanks to Zac Medico, there are new Python clients available for rqlite — a pure Python client, and a SQLAlchemy mapper. Check them out on GitHub.
To help with the growth of rqlite, it’s been moved to a new repository, under a dedicated organization. Github made this transfer very easy. I decided on a new logo too.
rqlite is a replicated relational database built on SQLite, with distributed consensus provided by the Raft consensus protocol. It gracefully handles leader election, and can tolerate machine failure. Written in Go, v2.2.1 is out now.
I made a presentation on rqlite tonight at the San Francisco Go Meetup. It was an enjoyable evening, and I had a chance to discuss why I built rqlite, how it works, and where it might go in the future.
Programming a database is fascinating work. I’ve been deeply involved with developing open source databases for the past two years and programming a database is possibly the most instructive project one can ever complete as a software developer. What’s really…
rqlite is a replicated SQLite database, with distributed consensus provided by the Raft consensus protocol. Written in Go v2.0 is now out. This release is a significant upgrade relative to v1.0.
rqlite provides robust replication for SQLite databases using the Raft consensus protocol. Coded in Go it ensures that all changes made to the leader SQLite database are replicated to all other nodes in the cluster, providing fault-tolerance and reliability. It’s been 18 months since…
I’ve started replacing go-raft within rqlite with the implementation from Hashicorp. go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd. I’m also going to change the API, so…
I recently presented at the InfluxDB San Francisco Meetup, on InfluxDB and the Raft consensus protocol. My talk was about the fundamental problems of distributed systems, and how InfluxDB uses Raft to solve these issues.
When you’d like to contribute to an open-source project it can be difficult to know where to start. Check out my latest post for the InfluxDB blog, explaining how we on the Core team have curated a set of issues,…
Another post for the InfluxDB blog — on testing the storage engines within InfluxDB. You can check it out here.
I always use the names of economists for my machines’ hostnames. keynes, friedman, marx, fisher, ricardo. So every so often the strange economics of open-source software hits me.
The first version of the 0.9.0 series of InfluxDB has been released. It’s alpha-quality software but all of us on the InfluxDB team are very excited to see the software reach this stage. You can read more about the release…
Packt recently asked me to review their new publication Cassandra High Availability, written by Robbie Strickland. I’ve worked with Cassandra in the past — early designs of Loggly‘s 2nd generation Log analytics platform used Cassandra as its authoritative store for…
SQLite is a “self-contained, serverless, zero-configuration, transactional SQL database engine”. However, it doesn’t come with replication built in, so if you want to store mission-critical data in it, you better back it up. The usual approach is to continually copy…
This blog describes working with InfluxDB 0.8. InfluxDB 0.8 is no longer supported, and has been superseded by the 1.0 release. I recently came across InfluxDB — it’s a time-series database built on LevelDB. It’s designed to support horizontal as…
Cassandra is an open-source, distributed database, informally known as a NoSQL database. It is designed to store large amounts of data, offer high-write performance, and provide fault-tolerance. I recently needed some hands-on experience with Cassandra, and being relatively new to…
