  • Optimized approach to parallelize writing to a shared memory resource
    Patent number: 8745352
    Abstract: Reducing contentions between processes or tasks that are trying to access shared resources is described herein. According to embodiments of the invention, a method of writing a set of data associated with a task to a memory resource is provided. The method includes calculating the amount of memory required to write said data to the memory resource and updating an expected end marker to reflect the amount of memory required to write the data to the memory resource. A flag is then set to an incomplete state, and the data is written to the memory resource. The flag can be set to a complete state and an end marker is updated. The end marker indicates the end of the data stored in the memory resource.

  • Statement logging in databases
    Patent number: 8676749
    Abstract: System, method, computer program product embodiments and combinations and sub-combinations thereof for logging of data manipulation language (DML) statements are described herein. An embodiment includes a database engine, a replication agent and a replication server which replicates data from the database engine to one or more replicate databases. The database engine writes parsed query information into a transaction log so that a process of replication agent may read the parsed query information and forward it to the replication server. The database engine writes all log records associated with a statement in a manner that allows the replication server to distinguish if those log records belong to same statement. In another embodiment, replication agent selectively sends SQL statement information to the replication server based on the replication server architecture.

  • Plan Caching Using Density-Based Clustering
    Publication number: 20130318069
    Abstract: A query plan predictor receives a query instance according to a query template having a set of parameters. The query plan predictor determines a plan space point for the query instance which is based upon the set of parameters. The query plan predictor predicts a predicted query plan for the plan space point, which is selected from a map of query plans according to a confidence threshold from a plan cache that includes at least one histogram. Each histogram is representative of a cached query plan in the plan cache combined with a previously-selected locality-sensitive hashing function. The histogram stores a frequency distribution of a mapping of sample plan points for the cached query plan by the locality-sensitive hashing function.

  • System and method for synchronizing message processing in a continuous processing system
    Patent number: 8560495
    Abstract: A system and method to synchronize the processing of messages in areas of an execution graph affected by primitives with potential for substantial delay is provided. A continuous processing system identifies primitives with potential for substantial delay. For each potentially-delayed primitive that is not in a loop, the continuous processing system creates a “timezone” downstream of such primitive. The output(s) of the potentially-delayed primitive is an input to the timezone. The continuous processing system then identifies all other inputs to the timezone and places a synchronizer across such inputs. In cases where the potentially-delayed primitive is within a loop, the timezone includes such primitive, as well all primitives downstream of such primitive.
