Abstract: In accordance with an embodiment, described herein is a system and method for use of lock-less data structures and processes with a multidimensional database computing environment. Lock-less algorithms or processes can be implemented with specific hardware-level instructions so as to provide atomicity. A memory stores an index cache retaining a plurality of index pages of the multidimensional database. A hash table indexes index pages in the index cache, wherein the hash table is accessible by a plurality of threads in parallel through application of the lock-less process.

Abstract: In accordance with an embodiment, described herein is a system and method for use with a multidimensional database computing environment. Particularly, a system and method are described for performing in-place data writes to a data storage medium associated with the multidimensional database computing environment. For example, when multiple data updates from calculation scripts are associated with a same set of blocks, the in-place data enable the system to reduce fragmentation of the data storage medium, and also to reduce contention due to index updates.
