Apache Crunch is a Java library for writing, testing, and running MapReduce pipelines. One of Crunch's goals is to make it easy to write and test pipelines that process complex records containing nested and repeated data structures, like protocol buffers and Thrift records. This module contains support for Crunch's PType serialization for Elephant Bird's ProtobufWritable and ThriftWritable classes, along with Source, Target, and SourceTarget implementations to support Elephant Bird's LzoProtobufBlockInputFormat, LzoThriftBlockInputFormat, LzoProtobufBlockOutputFormat, and LzoThriftBlockOutputFormat.
