I wouldn’t recommend adding this mode as a solution to schema mismatches. New segments generated through batch or streaming ingestion using the updated schema would still have the new column type, so the table could encounter the same query merge failures. Changing an existing column’s data type is backward incompatible. If users need to make that change, they need to refresh all segments in the table so the stored types consistently match the new schema. Queries may still fail during the transition while old and new types coexist; an index-only refresh would leave that underlying incompatibility unresolved. -- This is an automated message from the Apache Git Service.
