Abstract
Techniques are described herein for supporting pipelining operations involving DML (Data manipulation Language) and query. In an embodiment, a DML operation is performed for the purpose of changing data in a database system from a first state to a second state. Before the data in the database system is changed by the DML operation, the DML operation has an in-memory representation of such data. In an embodiment, a subsequent query operation that logically depends on the data in the database system in the second state is granted access to the in-memory representation of such data in the second state before the data in the database system is changed by the DML operation to the second state. As a result, operations may be executed in a pipelined fashion with minimum blocking.
