## What it is
Hollywood is a fast, lightweight actor model engine for Go, supporting local and clustered distributed actors with guaranteed message delivery. It uses dRPC and optimized protobufs as transport and targets low-latency, high-throughput workloads.

## Use cases
- build a game server with concurrent actors in Go
- write a low-latency trading engine
- implement fault-tolerant microservices with the actor model
- run distributed self-discovering actor clusters
- handle millions of messages per second between actors
- build an advertising broker backend

## When to choose
- you need extremely high message throughput and low latency in Go
- you want lightweight actor semantics with clustering support
- you need WASM compatibility for actor-based code
- you want guaranteed delivery on actor failure

## When to avoid
- you need a mature ecosystem like Akka with years of production hardening
- you only need simple background job queues rather than actor messaging
- your stack is not Go
- you need rich supervision and persistence features out of the box

## Facets
- artifact type: library
- maturity: active
- function: concurrency, rpc, message-queue, microservices
- domain: microservices, backend, performance
- platform: go, windows, wasm
- tags: actor-model, actor-framework, low-latency, cluster, fault-tolerance, drpc, protobuf, real-time, linux, macos
