## What it is
The official AWS SDK library for writing AWS Lambda functions in Go, providing the lambda.Start handler registration, event type definitions, and build tooling like build-lambda-zip. It lets Go developers implement serverless handlers that AWS Lambda invokes via RPC.

## Use cases
- write aws lambda functions in go
- handle s3 events in a go lambda
- build a serverless api backend with go
- process sqs messages with a go lambda handler
- cross-compile a go binary for lambda's provided runtime
- package a go binary into a lambda deployment zip

## When to choose
- you are developing AWS Lambda functions in Go
- you need typed event structs for Lambda triggers like S3, SQS, or API Gateway
- you want the official, AWS-maintained runtime client for the provided.al2/al2023 runtimes

## When to avoid
- you are writing Lambda functions in another language like Python or Node.js
- you are deploying Go services outside AWS Lambda
- you need a full web framework rather than a Lambda handler library
