Binary data or data that can be converted to a byte array can be stored in an HBase column. You can read from and write to an HBase tables in bytes.
When you create a data object, you can choose to get all the columns in a column family as a single stream of binary data.
Use the HBase data object as a source to read data in all the columns in the column family as a single stream of binary data. Use the HBase data object as a target to write data in all the columns in the source data object as a single column of binary data in the target HBase table.
The Data Integration Service generates the data in the binary column based on the protobuf format. Protobuf format is an open source format to describe the data structure of binary data. The protobuf schema is described as messages.
