> I would have used GenericDatumReader with reader and writer schema, but first I wanted to append new evoluted events to an existing file In HUDI log files, records are added to AvroDataBlock which have a header containing the schema for the writer. Different AvroDataBlock could have different schemas but all records within the same block should have the same schema. Log blocks are read using both reader/write schema. https://github.com/apache/hudi/blob/master/hudi-common/src/main/java/org/apache/hudi/common/table/log/block/HoodieAvroDataBlock.java#L143 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
