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)
