Export: Avro

Converts the data contract into an Avro schema. It supports specifying custom Avro properties for logical types and default values.

datacontract export avro datacontract.yaml --output schema.avsc

Custom Avro properties

A config map on property level may include additional key-value pairs. At the moment, logicalType and default are supported.

schema:
  - name: orders
    properties:
      - name: my_field_1
        description: Example for AVRO with Timestamp (microsecond precision)
        logicalType: integer
        physicalType: long
        examples:
          - 1672534861000000  # 2023-01-01 01:01:01 in microseconds
        required: true
        config:
          avroLogicalType: local-timestamp-micros
          avroDefault: 1672534861000000

• avroLogicalType — the Avro logical type of the property (here local-timestamp-micros).
• avroDefault — the default value for the property in Avro.
