For example, you can configure parquet.compression=GZIP to enable gzip compression. Data Type Mapping. Currently, Parquet format type mapping is compatible with Apache Hive, but different with Apache Spark: Timestamp: mapping timestamp type to int96 whatever the precision is. Parquet output format is available for dedicated clusters only. You must have Confluent Cloud Schema Registry configured if using a schema-based output message format (for example, Avro). "compression.codec": Sets the compression type. Valid entries are AVRO - bzip2, AVRO - deflate, AVRO - snappy, BYTES - gzip, or JSON - gzip.

Using Parquet as the output format allows you to output the Avro message to a file readable by a parquet reader, including Java AvroParquetOutputFormat类代码示例，parquet.avro.

The schema is saved in Parquet file for future readers to use.

Create your own objects. The ParquetOutputFormat can be provided a WriteSupport to write your own objects to an event based RecordConsumer. the ParquetInputFormat can be provided a ReadSupport to materialize your own objects by implementing a RecordMaterializer; See the APIs: // sparquet context can read and write parquet files into RDD of different avro schema types: val sc = new SparquetContext (" Example ") val requests: RDD [Request] = sc.parquetFile[Request](" /http/requests.parquet ") val responses: RDD [Response] = requests.map(intoResponse) responses.saveAsParquetFile(" /http/responses.parquet ") The following examples show how to use parquet.hadoop.ParquetOutputFormat.
