Lokesh Jain updated HUDI-6621:
------------------------------
Description:
In table version 6, we introduce a new delete block format (v3) with Avro serde
(HUDI-5760). For downgrading a table from v6 to v5, we need to perform
compaction to handle v3 delete blocks created using the new format.
Also with the addition of record index field in Metadata table schema, the
downgrade needs to delete the metadata table to avoid column drop errors after
downgrade.
