Structural Architecture

Redis maintains a beautifully self-contained, purely C-based structural organization. There are minimal dependencies, relying mostly on direct OS POSIX abstractions and a monolithic core executable setup managed plainly inside the `src` folder.

Uncompromising C simplicity. Minimal subdirectories, maximizing flat access.
Deep dependency encapsulation. Everything needed to build Redis completely isolated in the `/deps` directory.

Notable Directories

/src

The single, massive core directory containing everything from the CLI tools to the primary caching engine.

/deps

Embedded dependencies like jemalloc and hiredis, guaranteed to compile seamlessly without external package managers.

/tests

TCL-based test framework rigorously evaluating memory leaks and multi-threaded edge cases.
