Does corteza support batch insert or update like SQL syntax

SQL batch insert syntax like following:
INSERT INTO table_name (datetime, uid, content, type) VALUES (‘0’, ‘userid_0’, ‘content_0’, 0), (‘1’, ‘userid_1’, ‘content_1’, 1);

Does corteza support it?

If you’re accessing the DB directly – use the SQL syntax.
If you’re using the API – see here
