> 3. Batch delete: `merge_type: DELETE` is a good method for delete. If there are two records in a batch : one is delete and the other is append, `merge_type: MERGE` can solve , maybe is there a better method? @aihai Hello, I have an idea. You don't need to add `delete/merge` in the header. You can directly determine the delete event during streamload. Add `__DORIS_DELETE_SIGN__ =1` to the data and column to achieve the delete effect. for example: `curl -v --location-trusted -u root:123456 -H "format: json" -H "strip_outer_array: true" -H "jsonpaths: [\"$.id\", \"$.name\",\ "$.__DORIS_DELETE_SIGN__\"]" -H "columns: id,name,__DORIS_DELETE_SIGN__" -T example.json http://127.0.0.1:8030/api/test/test_delete/_stream_load` -- This is an automated message from the Apache Git Service.
