- **[Parquet] Files (for Protobuf messages)**: Columnar storage format. To use this output format, set `secor.file.reader.writer.factory=com.pinterest.secor.io.impl.ProtobufParquetFileReaderWriterFactory` option. In addition, Protobuf message class per Kafka topic must be defined using option `secor.protobuf.message.class.<topic>=<protobuf class name>`. If all Kafka topics transfer the same protobuf message type, set `secor.protobuf.message.class.*=<protobuf class name>`.
-- **[Parquet] Files (for JSON messages)**: JSON messages can be written to Parquet files. In addition to setting all options necessary for Protobuf messages, the JSON topics must be explicitly defined using the option `secor.topic.message.format.<topic>=JSON` or `secor.topic.message.format.*=JSON` if all Kafka topics use JSON.
+- **[Parquet] Files (for JSON messages)**: Columnar storage format. In addition to setting all options necessary to write Protobuf to Parquet, the JSON topics must be explicitly defined using the option `secor.topic.message.format.<topic>=JSON` or `secor.topic.message.format.*=JSON` if all Kafka topics use JSON. The protobuf classes defined per topic will be used as intermediaries between the JSON messages and Parquet files.
- **[Parquet] Files (for Thrift messages)**: Columnar storage format. To use this output format, set `secor.file.reader.writer.factory=com.pinterest.secor.io.impl.ThriftParquetFileReaderWriterFactory` option. In addition, thrift message class per Kafka topic must be defined using option `secor.thrift.message.class.<topic>=<thrift class name>`. If all Kafka topics transfer the same thrift message type, set `secor.thrift.message.class.*=<thrift class name>`. It is asumed all messages use the same thrift protocol. Thrift protocol is set in `secor.thrift.protocol.class`.
-- **[Parquet] Files (for Avro messages)**: Columnar storage format. To use this output format, set `secor.file.reader.writer.factory=com.pinterest.secor.io.impl.AvroParquetFileReaderWriterFactory` option. In addition, thrift message class per Kafka topic must be defined using option `secor.thrift.message.class.<topic>=<thrift class name>`. The `schema.registry.url` option must be set.
+- **[Parquet] Files (for Avro messages)**: Columnar storage format. To use this output format, set `secor.file.reader.writer.factory=com.pinterest.secor.io.impl.AvroParquetFileReaderWriterFactory` option. The `schema.registry.url` option must be set.
- **Gzip upload format**: To enable compression on uploaded files to the cloud, in `secor.common.properties` set `secor.compression.codec` to a valid compression codec implementing `org.apache.hadoop.io.compress.CompressionCodec` interface, such as `org.apache.hadoop.io.compress.GzipCodec`.
