Purely Functional
fs2-aws wraps the AWS SDK v2 async clients (and, for Kinesis, the KCL/KPL) in purely functional, resource-safe APIs built on cats-effect and FS2, sharing FS2's design goals: compositionality, expressiveness, resource safety, and speed.
Streaming
Read and write S3 objects, consume Kinesis and SQS, publish to SNS, and scan DynamoDB tables as back-pressured FS2 streams and pipes — processing large payloads in constant space.
