I ask your this question because I created a `MERGE_ON_READ` hudi table and found that hudi use `org.apache.hudi.common.model.HoodieAvroPayload` as payload class in `/.hoodie/hoodie.properties` and not `OverwriteWithLatestAvroPayload`. ``` hoodie.compaction.payload.class=org.apache.hudi.common.model.HoodieAvroPayload hoodie.table.name=brand_extension_areader hoodie.archivelog.folder=archived hoodie.table.type=MERGE_ON_READ hoodie.timeline.layout.version=1 ``` I remember in the old version (0.4.5? or older), hoodie use `HoodieAvroPayload` and didn't have `OverwriteWithLatestAvroPayload`. So I think any class implements `HoodieRecordPayload` maybe support delete function.
