Clients speak <strong>RESP</strong> over TCP; the process stores keys in logical databases and serves commands from a single-threaded event loop that owns the keyspace. Logical types (string, list, set, …) are separate from physical <strong>encodings</strong> chosen for memory and CPU cost.</p> <p>This post covers <strong>general concepts</strong>, <strong>process architecture</strong>, and the <strong>type / encoding</strong> map as implemented in current Redis source (<code>server.h</code>, <code>object.h</code>, <code>server.c</code>).</p>https://kevinwang930.github.io/post/data/redis/build/Sat, 18 Jul 2026 10:38:29 +0700https://kevinwang930.github.io/post/data/redis/build/<p>How to build Redis from source on Fedora, configure a non-default port, and open the tree in CLion.
