Abstract
Techniques are provided for managing in-memory space and objects. In one embodiment, a set of in-memory objects are maintained within an area in volatile memory that is accessible to a database server. An in-memory object in this context includes a set of one or more in-memory segments where each respective in-memory segment includes a set of in-memory extents and each respective in-memory extent is a contiguous chunk of memory from the area in volatile memory that is accessible to the database server. The area in volatile memory is managed as a set of stripes, where each stripe is a contiguous chunk of in-memory extents. Stripe control blocks are used to locate free in-memory extents for allocation and registration with an in-memory segment.
