The extraordinary simple, performant, and extensible custom AWS Lambda runtime for Clojure.

The extraordinary simple, performant, and extensible custom AWS Lambda runtime for Clojure.

Holy Lambda supports multiple backends

• Babashka,
• Native Clojure (GraalVM compiled),
• Clojure (much faster than official AWS Java runtime),

Incoming

• nbb
• ClojureScript

Goals

• Low cold starts - Clojure goes fast on AWS Lambda!
• Multiple backends support - Unified runtime for Clojure/script!
• Minimal API - Just stuff that gets the job done!

Non-Goals

• Tight integration with deployment tools - I don't want to do this!

Companies & Inviduals using Holy Lambda?

• nextdoc.io - 6 native lambdas: api-gateway custom authorizer, file access control, openapi data source etc.
• scalably.ai - 14 native lambdas: xml transformations, sftp interactions, message routing, encryption etc.
• retailic - native lambda that uses compatibility layer with ring, regular Clojure api on ARM64

Extensions

• holy-lambda-ring-adapter - Supports running full featured Ring apps on AWS Lambda

Resources
