  • Patent number: 10936562
    Abstract: A database system stores both compressed and uncompressed data in a row-based database system. The database system converts a representation of data involving a set of rows of a source database table, each row comprising multiple values, into a representation involving a single row stored in a target database table, each column of the row comprising arrays of values from the set. The database system may perform type-specific compression of data when storing in the target database table. Accordingly, the database system may apply different compression schemes for different columns or sets of values obtained from the source database table and may group or order selected rows or store additional summary information to improve query performance to the target database table. The database system allows users to query data stored in compressed form. The database system combines compressed and uncompressed data at query time for efficient database analytics.

  • Patent number: 10482021
    Abstract: In an aspect, high priority lines are stored starting at an address aligned to a cache line size for instance 64 bytes, and low priority lines are stored in memory space left by the compression of high priority lines. The space left by the high priority lines and hence the low priority lines themselves are managed through pointers also stored in memory. In this manner, low priority lines contents can be moved to different memory locations as needed. The efficiency of higher priority compressed memory accesses is improved by removing the need for indirection otherwise required to find and access compressed memory lines, this is especially advantageous for immutable compressed contents. The use of pointers for low priority is advantageous due to the full flexibility of placement, especially for mutable compressed contents that may need movement within memory for instance as it changes in size over time.

  • Patent number: 10009446
    Abstract: One embodiment provides a system in a first node that facilitates efficient packet forwarding. During operation, the system identifies a type, length, and value (TLV) string in a packet and, in response, generates a compressed representation of the TLV string. The system stores the compressed representation for the TLV string in an entry of a learned dictionary in a storage device of the first node. The system then sends the entry to a second node and, in response, receives an acknowledgement from the second node. If the system identifies the TLV string in a subsequent second packet of the acknowledgement, the system compresses the TLV string in the second packet based on the compressed representation.

  • Patent number: 9998322
    Abstract: Methods for balancing storage data traffic in a system in which at least one computing device (server) coupled to a converged network accesses at least one storage device coupled (by at least one adapter) to the network, systems configured to perform such methods, and devices configured to implement such methods or for use in such systems. Typically, the system includes servers and adapters, and server agents implemented on the servers and adapter agents implemented on the adapters are configured to detect and respond to imbalances in storage and data traffic in the network, and to redirect the storage data traffic to reduce the imbalances and, thereby to improve the overall network performance (for both data communications and storage traffic). Typically, each agent operates autonomously (except in that an adapter agent may respond to a request or notification from a server agent), and no central computer or manager directs operation of the agents.

  • Patent number: 9916822
    Abstract: A derivative track for an audio track may be generated. An audio track duration of the audio track may be partitioned into partitions of a partition size. A current partition may be compared to remaining partitions of the audio track. Audio information for the current partition may be correlated to audio information for remaining partitions to determine a correlated partition for the current partition from among the remaining partitions of the track duration. The correlated partition determined may be identified as most likely to represent the same sound as the current partition. This comparison process may be performed iteratively for individual ones of the remaining partitions. One or more regions of the audio track may be identified. Individual regions may include multiple correlated partitions that are temporally adjacent along the audio track duration. One or more partitions within one or more regions may be removed to generate the derivative track.
