摘要： A data recovery system and method are disclosed. Primary data is stored a database in byte-addressable NVRAM, where the database includes one or more persistent tables of data in a byte-addressable, RAM format, and a persistent memory allocator that maps persistent memory pointers of the persistent memory to virtual memory pointers of a virtual memory associated with the database. Secondary data is stored in volatile DRAM. A failure recovery includes recovering the persistent memory allocator, mapping the persistent memory to the virtual memory to recover primary data using their persistent memory pointers, translating the persistent memory pointers to virtual memory pointers, undoing changes to the primary data made by unfinished transactions of the query execution at the time of failure of one of the one or more queries, and reconstructing the secondary data from the primary data.

摘要： One embodiment of the present invention provides a method for incrementally maintaining a Bernoulli sample S with sampling rate q over a multiset R in the presence of update, delete, and insert transactions. The method includes processing items inserted into R using Bernoulli sampling and augmenting S with tracking counters during this processing. Items deleted from R are processed by using the tracking counters and by removing newly deleted items from S using a calculated probability while maintaining a degree of uniformity in S.

摘要： A system, computer-implemented method, and computer-readable storage medium for generating a block-based index, are provided. A block index is generated where the block index comprises a plurality of blocks and a block corresponds to a section of a graph column that stores a value. A block range vector is also generated for the index where the block range vector includes range information for the block that corresponds to the section of the graph and where the block-based index facilitates traversal of the graph column that searches for the value by constraining the traversal to the section of the graph.

摘要： Technologies are disclosed for generating query execution plans optimized for parallel execution for programs having both core database relational functions and user-defined functions. A variety of optimization strategies can be employed to improve performance in a parallel execution scenarios. A flexible range of permitted partition arrangements can be specified as acceptable to parallelized instances of the user-defined function. The optimizer can leverage such information when constructing an optimized query execution plan. Partitioning arrangements or other properties can be leveraged to avoid additional or unnecessary processing.
