CDAP vs s3-lambda: What are the differences?
CDAP: Open source virtualization platform for Hadoop data and apps. Cask Data Application Platform (CDAP) is an open source application development platform for the Hadoop ecosystem that provides developers with data and application virtualization to accelerate application development, address a broader range of real-time and batch use cases, and deploy applications into production while satisfying enterprise requirements; s3-lambda: Lambda functions over S3 objects: each, 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.
CDAP and s3-lambda can be categorized as "Big Data" tools.
CDAP and s3-lambda are both open source tools. s3-lambda with 1.06K GitHub stars and 43 forks on GitHub appears to be more popular than CDAP with 346 GitHub stars and 178 GitHub forks.
