Aspects of the present invention provide high-performance indexing for data-intensive systems in which “slicing” is used to organize indexing data on an SSD such that related entries are located together. Slicing enables combining multiple reads into a single “slice read” of related items, offering high read performance. Small in-memory indexes, such as hash tables, bloom filters or LSH tables, may be used as buffers for insert operations to resolve slow random writes on the SSD. When full, these buffers are written to the SSD. The internal architecture of the SSD may also be leveraged to achieve higher performance via parallelism. Such parallelism may occur at the channel-level, the package-level, the die-level and / or the plane-level. Consequently, memory and compute resources are freed for use by higher layer applications, and better performance may be achieved.

Systems, methods and computer program product embodiments for auto-correction in database replication are disclosed herein. An embodiment includes receiving a log record of one or more database row changes on a table marked for replication. From the received log record, one or more insert operations on the marked table are identified. Each identified insert operation is automatically replaced with a first pair of operations, where each first pair comprises a delete operation associated with a new insert operation. Each first pair, when executed at a replicate database, acts to delete data at a first location identified by each identified insert operation prior to inserting data of the new insert operation at the first location. The embodiment further includes identifying, from the log record, one or more update operations on the marked table, and automatically replacing each identified update operation with a second pair of operations, where each second pair comprises a new delete operation associated with a new insert operation.

The invention concerns a method and a system for maintaining consistency of a cache memory, accessible by multiple independent processes. The processes can share common data. The processes perform simultaneous data searching operations optionally followed by providing the data to the processes, a removal of same or an insertion of new data. The searching, removal and insertion operations, are comprehensively executed once they have been initiated by the independent processes. They are executed excluding one another when they must operate on common data. The removal or insertion operations are each completely reversible. In that context, the invention provides that the operations for providing, removing or inserting the data have a finite or bound duration of execution so as to prevent any locking. In particular, the insertion operation, which includes a step of releasing an input when a partition of the cache memory is full, if it requires browsing through the entire partition to make a selection, is however possibly interrupted if the maximum browsing time is reached. In that case, the most appropriate input, among the already browsed inputs, is released. The inputs of said partition are browsed exhaustively, which results from storing the last consulted address of the partition after each release.

The invention relates to a remote sensing image block sorting and storing method suitable for spatial query, which comprises the following steps: regularly dividing an image into 22n image blocks from the top left corner; establishing a sorting queue for the image blocks according to the Hilbert sequence; marking front 2n-1 node pairs with maximum correlative sorting distance on the nth order of the Hilbert sequence, wherein each node pair comprises a node ai and a node bi, the ai and the bi indicate nodes in the node pair with maximum ith sorting distance, and i is greater than 0 and less than 2n-1+1, and inserting the nodes in the node pair into the sorting queue; repeating the marking and inserting operations in step 3 for n-1 orders corresponding to four quadrants of the Hilbert sequence until the mth order which is assigned by a user and meets performance requirements, and finally, generating a new sorting queue (i.e. improved Hilbert sequence); and according to the sequence in the sorting queue, storing practical image block data and minimum external frames of the blocks in an object-relational database. The invention provides an efficient method for organizing and storing alarge amount of image data on storage equipment, such as disks and the like, thereby improving the spatial query efficiency of remote sensing images.

A hand-held sampling apparatus used for an ion mobility spectrometer and method of obtaining a sample are provided to prevent deformation of sampling wipes when detecting explosives and drugs. The apparatus has a body comprising a handle in the rear portion and a wiping sampling mechanism in the front portion, with a wiping surface located on its underside. The sampling wipe can be in full contact with the surface of the object during wiping to improve wiping efficiency. Correspondingly, a smaller sample inlet port can be disposed on the analyzer so as to save a large amount of sampling wipes. and meanwhile avoid sampling wipes from deformation and folds hard to restore, thereby ensuring subsequent sample insertion operation, enhancing the efficiency of both sample collection and sample injection and improving the detection performance for the analytes to be detected. The method of using said sampling device according to the present invention comprises the following steps: attaching a sampling wipe to the swiping surface; fixing the front end portion of the sampling wipe by using the front holder, and fixing the rear end portion of the sampling wipe by using the rear holder. The method of the present invention is simple and convenient.
