How to organise a Go project
Some fellow developers, using Go for the first time, recently asked me how to organise a Go project and for some high-level guidance on programming using the language. I thought the most effective way to answer this question was to…
rqlite v3: Globally replicating SQLite
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 v3.0.1 released with leader redirection
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…
rqlite moved to new repository
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 v2.2.1 released with HTTPS, Basic Auth, and user permissions
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.
rqlite at the San Francisco Go Meetup
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.
rqlite 2.0 released with configurable read-consistency
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 – replicated SQLite with new Raft consensus and API
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…
rqlite and Hashicorp Raft Consensus
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 go-raft is no longer maintained, and I’ve good experience with the Hashicorp code, due to my work with InfluxDB and hraftd.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…
New browser interface for Ekanite
Ekanite is an open-source Syslog server with built in log search. Thanks to some nice work by Fabian Zaremba, Ekanite now supports searching your logs via a browser. If you’d like to understand more about the design and development of…
Revisiting syslog-gollector
It’s been 18 months since the first commit to my first significant Go project — syslog-gollector. After an initial burst of activity to create a functional Syslog Collector that streamed to Apache Kafka, the source code hadn’t been updated much…
InfluxDB and the Raft consensus protocol
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.
Designing a search system for log data — part 3
This is the last part of a 3-part series “Designing and building a search system for log data”. Be sure to check out part 1 and part 2. In the last post we examined the design and implementation of Ekanite,…
Designing a search system for log data — part 2
This is the second part of a 3-part series “Designing and building a search system for log data”. Be sure to check out part 1. Part 3 follows this post. In the previous post I outlined some of the high-level…
Designing a search system for log data — part 1
This is the first part of a 3-part series “Designing and building a search system for log data”. Part 2 is here, and part 3 is here. For the past few years, I’ve been building indexing and search systems, for…
Contributing to InfluxDB
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,…
Testing InfluxDB Storage Engines
Another post for the InfluxDB blog — on testing the storage engines within InfluxDB. You can check it out here.
Building a distributed key-value store using Raft
Hashicorp provide a nice implementation of the Raft consensus protocol, and it’s at the heart of InfluxDB (amongst other systems). I wanted to experiment with a simple system built using this particular Raft implementation, so was inspired by raftd to…
Coding like it’s 1999
“Run into an obstacle in what you’re working on? Hmm, I wonder what’s new online. Better check.” If you haven’t already, you should start reading Paul Graham’s essays. In one on philosophy, Graham believes that many of the answers provided…
Who watches the watchers?
I’ve written my first post for the InfluxDB blog. In it I discuss the new statistics and monitoring system built into InfluxDB, starting with the 0.9.4 release. Functionality like this is critical when it comes to running a distributed database…
400 days of Go
It’s been 418 days since my first Github commit of Go code. In that time I’ve written a Syslog-to-Kafka producer, a Raft-based distributed SQLite database, a near real-time log search system, and become a core developer of InfluxDB.
Gophercon 2015
This past week I attended Gophercon 2015, in Denver, CO. It was also a chance to get together with the rest of the InfluxDB team. And because the Go community is still relatively young and small, it was a great…
