Delete data
Deletes rows from a table. The request has the same path, headers, and JSON array body as Set data, including the limit of 2000 objects per request. Each object only needs the primary key columns for that row. Read Table metadata to see which columns haveis_primary_key set to true.
The batch is applied as a whole. Every row in the request is deleted, or none of them are.
Send every primary key column when the table uses a composite key. Other columns can be omitted.
