Change subject: core: early return in batch operations with no elements ...................................................................... core: early return in batch operations with no elements Seems like currently on every batch operation (save/update/remove) we use a connection to the database. Not all the callers to these operations verify that there are actually elements in the collection of entities they pass. Therefore, we go deep into the stack and get a connection to the database in order to execute stored procedure that doesn't do anything. As a solution, this patch suggests to return early without doing anything in these operations when the passed collection of entities is empty.
