Apache Falcon

Falcon is a feed processing and feed management system aimed at making it easier for end consumers to onboard their feed processing and feed management on hadoop clusters.

Why Apache Falcon?

  • Dependencies across various data processing pipelines are not easy to establish. Gaps here typically leads to either incorrect/partial processing or expensive reprocessing. Repeated duplicate definition of a single feed multiple times can lead to inconsistencies / issues.

  • Input data may not arrive always on time and it is required to kick off the processing without waiting for all data to arrive and accommodate late data separately

  • Feed management services such as feed retention, replications across clusters, archival etc are tasks that are burdensome on individual pipeline owners and better offered as a service for all customers.

  • It should be easy to onboard new workflows/pipelines

  • Smoother integration with metastore/catalog

  • Provide notification to end customer based on availability of feed groups (logical group of related feeds, which are likely to be used together)

Online Documentation

You can find the documentation on Apache Falcon website.
