I/O Connectors

Apache Beam I/O connectors provide read and write transforms for the most popular data storage systems so that Beam users can benefit from native optimised connectivity. With the available I/Os, Apache Beam pipelines can read and write data from and to an external storage type in a unified and distributed way.

I/O connectors denoted via X-language have been made available using the Apache Beam multi-language pipelines framework.
