Apache Avro is a remote procedure call and data serialization framework developed within the Hadoop project of Apache. It uses JSON for defining data types and protocols, and serializes data in a compact binary format. Its primary use is in Apache Hadoop, where it can provide both a serialization format for persistent data, and a wire format for communication between Hadoop nodes, and from client programs to the Hadoop services.
This appendix describes the available components in iWay Service Manager (iSM) that have been developed to integrate with Apache Avro.
