How the high performance and low latency of Apache APISIX is achieved

How are the high performance and low latency of Apache APISIX derived? What is its technical implementation?

Solution

There are several things that APISIX leverages to achieve high performance and low latency. Such as:

1. Using etcd as the configuration center.

It is a reliable data store that provides a watch mechanism, using this, APISIX becomes aware of the changes in near-realtime. Unlike other API Gateways that poll the database for updates.

2. High-Performance Route Matching Algorithm

It uses a radix-tree based high performance route matching algorithm that also supports fuzzy matching.

3. Hashtable-based IP matching algorithm.
