  • MANAGING STORAGE OF INDIVIDUALLY ACCESSIBLE DATA UNITS
    Publication number: 20090287986
    Abstract: A method includes determining a length of a file and storing the length of the file in a first memory location. An endpoint of a last complete record within the file is determined and the endpoint is stored in a second memory location. The length of the file stored in the first memory location is compared to a current length of the file, and a data structure associated with the file is updated beginning at the endpoint if the current length of the file exceeds the length of the file stored in the first memory location.

  • Managing Storage of Individually Accessible Data Units
    Publication number: 20080104149
    Abstract: A method for managing data includes receiving individually accessible data units, each identified by a key value; storing a plurality of blocks of data, each of at least some of the blocks being generated by combining a plurality of the data units; and providing an index that includes an entry for each of the blocks. One or more of the entries enable location, based on a provided key value, of a block that includes data units corresponding to a range of key values that includes the provided key value.

  • Managing computing resources in graph-based computations
    Publication number: 20070271381
    Abstract: Executing graph-based computations includes: accepting a specification of a computation graph in which data processing elements are joined by linking elements; dividing the data processing elements into sets, at least one of the sets including multiple of the data processing elements; assigning to each set a different computing resource; and processing data according to the computation graph, including performing computations corresponding to the data processing elements using the assigned computing resources.
