## What changes were proposed in this pull request? When the data is read from the sources, the catalyst schema is always nullable. Since Avro uses Union type to represent nullable, when any non-nullable avro file is read and then written out, the schema will always be changed. This PR provides a solution for users to keep the Avro schema without being forced to use Union type. ## How was this patch tested? One test is added. Closes #24682 from dbtsai/avroNull.
