Re-examining our approach to memory mapping

How does QuestDB get the kind of performance it does, and how are we continuing to squeeze another 50-60% out of it? We are constantly learning more about the fundamental concepts of memory performance, and this is one example of how what we at first thought would be worse for performance ended up bringing us a rather substantial boost in overall memory performance.

We will walk you through how some of our initial thoughts on storage and memory-mapping evolved to bring us better performance overall.

InfluxDB line protocol on QuestDB

We've had a UDP version of the InfluxDB Line Protocol (ILP) reader in QuestDB for quite some time, but we've had customers ask for a TCP version of it, so we delivered!

Using it, and configuring it, are relatively simple so don't expect this to be a long post but I'll walk you through the basics of how to set it up and use it. For an added bonus I'll show you how to migrate from using InfluxDB to using QuestDB with a less than a line of configuration.

IoT on QuestDB

As you can well imagine, I've been super busy in my hew job at QuestDB so this has taken me longer than I would have liked, but here we are. If you know me at all, you know that one of the first things I always do with new things is, well, connect things to them! So I immediately went to connect an IoT device to QuestDB to see how it went. Unsurprisingly, it went quite well. So here's how it went, from start to finish.
