Streamload error

load by MERGE or DELETE need to upgrade table to support batch delete

Refer to Doris batch delete function

resolvent

I set the parameters and restart Fe
to find that the table still does not support this function
it needs to be re created or manually executed to dynamically change the configuration.

Batch the unique test table_ Delete feature on (add hidden columns)

show create table csv_upload_test_unique
desc csv_upload_test_unique

set show_hidden_columns=true

alter table csv_upload_test_unique enable feature "BATCH_DELETE";

Then execute streamload
