This also facilitates use with dynamic, scripting languages, since data, together with its schema, is fully self-describing. Se hela listan på martin.kleppmann.com Avro is an open-source schema specification for data serialization that provides serialization and data exchange services for Apache Hadoop. Avro is a language-agnostic format that can be used for any language that facilitates the exchange of data between programs. The recommendation in my previous question was to set the schema, however I do not want to repeat myself writing the schema in both a .avro file and as sparks StructType and friends. How can I convert the avro schema (either text file or the generated MeObject.getClassSchema() ) into sparks StructType ? With Avro, it is not necessary to use a property to specify a specific type, since the type can be derived directly from the Avro schema, using the namespace and name of the Avro type.
