Orc Format

The Apache Orc format allows to read and write Orc data.

Here is an example to create a table using Filesystem connector and Orc format.

  user_id BIGINT,
  item_id BIGINT,
  category_id BIGINT,
  dt STRING
) PARTITIONED BY (dt) WITH (
 'path' = '/tmp/user_behavior',
)

Orc format type mapping is compatible with Apache Hive. The following table lists the type mapping from Flink type to Orc type.
