Command index¶

All 327 commands the server dispatches, derived at build time from the same source as src/commands/command_table.mojo (the table MULTI uses to reject unknown commands at queue time). A command that exists in the engine appears here; a command that appears here exists in the engine. The per-command semantics, return shapes and known divergences from Redis are in the Redis-compatible command matrix; the Pion-native families each have a reference page.

Redis-compatible (a Redis 8 command of the same name exists)	237
Pion-native	90

Redis-compatible¶

Arity is Redis's own (negative = at least that many); writes marks commands Redis flags as write commands, which is what decides WAL logging and WATCH bumps.
