Lambda functions over S3 objects with concurrency control (forEach, map, reduce, filter)

s3-lambda enables you to run lambda functions over a context of S3 objects. It has a stateless architecture with concurrency control, allowing you to process a large number of files very quickly. This is useful for quickly prototyping complex data jobs without an infrastructure like Hadoop or Spark.

At Littlstar, we use s3-lambda for all sorts of data pipelining and analytics.
