| # For the case of evolution, this test will try to start from a savepoint taken |
| # with 1.7 (same version) but in which the schema of the (old) avro type differs |
| # from the current one. The new schema adds an optional field with a default value |
| # to the old one and verifies that it can see the old value. |
| # |
| # The old avro schema of the Address data type was: |
| # |
| # {"namespace": "org.apache.flink.formats.parquet.generated", |
| # "type": "record", |
| # "name": "Address", |
| # "fields": [ |
| # {"name": "num", "type": "int"}, |
| # {"name": "street", "type": "string"}, |
| # {"name": "city", "type": "string"}, |
| # {"name": "state", "type": "string"}, |
| # {"name": "zip", "type": "string"} |
| # ] |
| # } |
| # |
| # while the new is: |
| # |
| # {"namespace": "org.apache.flink.avro.generated", |
| # "type": "record", |
| # "name": "Address", |
| # "fields": [ |
| # {"name": "num", "type": "int"}, |
