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.
