Inter-thread messaging is a fundamental part of any asynchronous system. It is the component responsible for the transportation of data between threads. Messaging forms the infrastructure, scaffolding multi-threaded applications, and just like real-world transport infrastructure, we want it to be inexpensive, fast, reliable, and clean. For QuestDB, we wrote our own messaging system, and this post is about how it works and how fast it is.

InfluxDB is the current market leader in time series. This post examines their ingestion format called InfluxDB line protocol (ILP) and compares data ingestion performance between QuestDB and InfluxDB. We'll look at data loss over UDP and some of the reasons why QuestDB is more efficient at ingesting records in ILP.
