!!! Attention !!!
This class is not meant to be used for concurrent operations on the same row inside the same batch.
If you are updating the same record twice or performing an update and delete of the same record in the same batch,
you should use timestamps to define a custom execution order.
In order to have concurrent operation on the same row in the same batch, custom timestamp needs to be inserted
on each statement, using the "timestamp" method available on every batchable query(INSERT, UPDATE, DELETE).
