A Ruby gem providing a generic lazy batching mechanism to avoid N+1 database or HTTP queries, inspired by Facebook's DataLoader and Haskell Haxl. It batches and caches data loads lazily wherever they are needed, with thread-safe loaders.

Use cases

• avoid N+1 database queries in a Rails app
• batch HTTP requests in a RESTful API
• resolve GraphQL fields efficiently with graphql-ruby
• cache previously loaded records with an identity map
• batch-load data lazily in a multi-threaded Ruby service

When to choose

• you have N+1 query problems in Ruby code or GraphQL resolvers
• you want a generic, framework-agnostic batching utility
• you need lazy, thread-safe batch loading with automatic caching

When to avoid

• you are not working in Ruby
• your data access is already efficiently batched by your ORM or framework
• you need eager preloading rather than lazy on-demand batching
