eolivelli opened a new pull request #9343:
URL: https://github.com/apache/pulsar/pull/9343
Fixes #9004
### Motivation
GenericRecord API exposes the list of `Fields` but not the datatype
associated to the field.
this patch introduces support for retrieving the `Schema` for each Field.
This information is available only for the limited subset of data types
supported by Pulsar, for instance Avro MAPS and ARRAYS are not implemented and
there is not way to represent such data types using SchemaType.
In the future when support for new datatype will be added we will support
those new types in this system.
The implementation covers Avro and JSON schema types.
With this implementation Pulsar IO support for Metadata will be more similar
the one in Kafka Connect, even we are still far as we do not have full support
for all AVRO datatypes.
### Modifications
- add new Field#getSchema method
- add new version of RecordSchemaBuilder#field that accepts a Schema instead
of a GenericSchema (` FieldSchemaBuilder field(String fieldName,
org.apache.pulsar.client.api.Schema<?> genericSchema);`)
- add relevant test cases
### Verifying this change
This change added tests.
I tested manually that on Sinks the information is available, there is no
need to add more integration tests
### Documentation
- Does this pull request introduce a new feature? yes
