摘要： A system for managing storage of data units includes a data storage system configured to store multiple data blocks, at least some of the data blocks containing multiple data units, with at least a group of the data blocks being stored contiguously, thereby supporting a first read operation that retrieves data units from at least two adjacent data blocks in the group. The system is configured to perform two or more operations with respect to data units. The operations include: a second read operation, different from the first read operation, that retrieves a data unit to be read based at least in part on an address of a data block containing the data unit to be read, and a delete operation that replaces a first data block containing a data unit to be deleted with a second data block that does not contain the deleted data unit.

摘要： Managing data by: receiving a group of individually accessible data units, each data unit identified by a key value, with key values determined such that the key value identifying a first data unit received before a second data unit occurs earlier in a sort order than the key value identifying the second data unit; and processing the data units for storage in a data storage system. The processing includes: storing blocks of data, the blocks being generated by combining a plurality of the data units; providing an index with entries that enable location, based on a provided key value, of a block that includes a data unit corresponding to the provided key value; and generating one or more screening data structures associated with the blocks for determining, based on a given key value, whether to search the stored blocks for a data unit corresponding to the given key value.

摘要： A method for performing a distributed computation on a computing system using computational resources dynamically allocated using a computational resource manager includes storing information specifying quantities of computational resources associated with respective ones of a number of program portions of the program, where the program portions perform successive transformations of data and each program portion uses computational resources granted by the computational resource manager enabling computation associated with that program portion to be performed in the computing system, requesting a first quantity of computational resources associated with a first program portion of the number of program portions from the computational resource manager, receiving a second quantity of computational resources from the computational resource manager, less than the requested first quantity of computational resources, performing computation associated with the first portion of the program using the second quantity of computational resources, while performing the computation associated with the first portion of the program using the second quantity of computational resources, receiving an additional quantity of computational resources from the computational resource manager, and performing an additional computation associated with the first portion of the program using the additional quantity of computational resources while performing the computation associated with the first portion using the second quantity of computational resources.

摘要： 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.

摘要： A system for managing storage of data units includes a data storage system configured to store multiple data blocks, at least some of the data blocks containing multiple data units, and configured to store, for at least some of the data blocks, corresponding historical information about prior removal of one or more data units from that data block, the removal affecting at least some addresses of data units in that data block. The system is configured to perform at least one operation that accesses at least a first data unit stored in a first data block according to address information interpreted based on any stored historical information corresponding to the first data block.
