System Documentation

What problem does it solve?

The js_lang component lets you write stored functions and procedures in JavaScript (V8 engine) instead of SQL/PSM, addressing scenarios where complex logic is more concise in JavaScript. It is tech preview in Percona Server 8.4 and executes in a sandbox with no file or network I/O, requiring installation of the component and the appropriate privileges.

Core Features & Use Cases

  • Write stored routines in JavaScript using the V8 engine, enabling clearer implementation for complex logic.
  • Sandbox execution with no file or network I/O; restricted environment to protect the database server.
  • Requires INSTALL COMPONENT 'file://component_js_lang' and the CREATE_JS_ROUTINE privilege; supports CREATE FUNCTION and CREATE PROCEDURE with LANGUAGE JS.

Quick Start

Install the component and grant the CREATE_JS_ROUTINE privilege, then create a JS-based routine using the LANGUAGE JS syntax.
