Abstract: A system includes creation of a first fragment of a first database column in a volatile memory system, reception of a first pointer to a first block of a second non-volatile memory system, the first block associated with the first fragment of the first database column, population of the first block of the second non-volatile memory system using the first pointer, while blocking creation of a database savepoint, commitment of the first block of the second non-volatile memory and association of a first block identifier of the first block of the second non-volatile memory with the first fragment of the first database column, and unblocking creation of the database savepoint.

Abstract: Disclosed herein are system, method, and computer program product embodiments for maintaining of a geometric object in a database. An embodiment operates by a database maintaining a first page storing a data block in the database's on-disk store such that the data block stores at least one byte of the geometric object. After receiving the request for the geometric object, the database loads the page storing the geometric object in the in-memory store and determines the size of the geometric object. Based on the size of the geometric object, the database stores the geometric object in the in-memory store directly or in a heap of the in-memory store.
