---------------------------
Summary: Not need to reWriteRecord when method
SchemaCompatibility.checkReaderWriterCompatibility return
SchemaCompatibilityType.COMPATIBLE
Key: HUDI-7436
URL: https://issues.apache.org/jira/browse/HUDI-7436
Project: Apache Hudi
Issue Type: Bug
Reporter: lei w
In HoodieMergeHelper#composeSchemaEvolutionTransformer we use this condition
_sameCols.size() != colNamesFromWriteSchema.size()
||
SchemaCompatibility.checkReaderWriterCompatibility(newWriterSchema,
writeSchemaFromFile).getType() ==
org.apache.avro.SchemaCompatibility.SchemaCompatibilityType.COMPATIBLE_ to
determine whether we need to rewrite record. The second condition may need to
be negated.
