ruby-batch-loader

Powerful tool to avoid N+1 DB or HTTP queries

Description

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.
