This library provides a generic lazy batching mechanism to avoid N+1 DB queries, HTTP queries, etc.

Highlights * Generic utility to avoid N+1 DB queries, HTTP requests, etc. * Adapted Ruby implementation of battle-tested tools like Haskell Haxl, JS DataLoader, etc. * Batching is isolated and lazy, load data in batch where and when it's needed. * Automatically caches previous queries (identity map). * Thread-safe (`loader`). * No need to share batching through variables or custom defined classes. * No dependencies, no monkey-patches, no extra primitives such as Promises.
