hello, my project use jpa + shardingjdbc when i use CrudRepository.save to save my data to database，jpa auto generated sql like update table_a set field_a = 1 , field_ab = 2 where id = 3 but my sharding-key is another field “dealership_id”。So my sql execute route to all data node. I would like to ask, is there any way to deal with this situation?
