Distributed Code Executor

A scalable Master–Worker based distributed system for executing untrusted user code in isolated sandboxes.

Features

Master-Worker Architecture

• Master exposes HTTP APIs for code submission & result retrieval.
• Workers pull tasks via RPC and execute them securely.

Task Queue + Pending Queue

• Task Queue: Stores tasks waiting for workers.
• Pending Queue: Tracks tasks currently being executed.
• Ensures retries even if a worker crashes.

Secure Sandboxed Execution

• Each task runs in a separate isolated environment.
