The Avro object encoded using Avro's binary encoding Implementations use the 2-byte marker to determine whether a payload is Avro. This check helps avoid expensive lookups that resolve the schema from a fingerprint, when the message is not an encoded Avro payload.

Avro. Avro conversion is implemented via the parquet-avro sub-project. 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:

ParquetOutputFormat.setWriteSupportClass(job, ProtoWriteSupport.class); は、その後protobufClass指定: ProtoParquetOutputFormat.setProtobufClass(job, your-protobuf-class.class); とアブロを使用して次のようなスキーマを導入してください: AvroParquetOutputFormat.setSchema(job, your-avro-object.SCHEMA); Parquet 格式也支持 ParquetOutputFormat 的配置。 例如, 可以配置 parquet.compression=GZIP 来开启 gzip 压缩。 数据类型映射. 目前,Parquet 格式类型映射与 Apache Hive 兼容,但与 Apache Spark 有所不同: Timestamp:不论精度,映射 timestamp 类型至 int96。 If, in the example above, the file log-20170228.avro already existed, it would be overridden.

These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You may check out the related API usage on the sidebar. The application logic requires multiple types of files getting created by Reducer and each file has its own Avro schema.

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).
