Detailed Description

A set of input parameters for deleteRecords(const DeleteRecordsRequest&) const.

Deletes record(s) matching the provided criteria from the given table. The record selection criteria can either be one or more expressions (matching multiple records) or a single record identified by record_id options. Note that the two selection criteria are mutually exclusive. This operation cannot be run on a collection or a view. The operation is synchronous meaning that a response will not be available until the request is completely processed and all the matching records are deleted.
