  • Publication number: 20220197873
    Abstract: Methods for page split detection and affinity in query processing pushdowns are performed by systems and devices. Page servers perform pushdown operations based on specific, and specifically formatted or generated, information, instructions, and data provided thereto from a compute node. Page servers also determine that page splits have occurred during reading of data pages maintained by page servers during pushdown operations, and also during fulfillment of compute node data requests. To detect a data page has split, page servers utilize information from a compute node of an expected next data page which is compared to a next data page in the page server page index. A mismatch in the comparison by page servers indicates data page was split. Compute nodes and page servers store and maintain off-row data generated during data operations via page affinity considerations where the off-row data is stored at the same page server as the data.

  • Publication number: 20220197892
    Abstract: Distributed database systems including compute nodes and page servers are described herein that enable compute nodes to pushdown certain query processing compute tasks to the page servers to take advantage of otherwise idle compute resources at the page servers, and to reduce the quantity of data that moves between compute nodes and page servers. A distributed database system includes a page server and a compute node, wherein the page server is configured to maintain multiple versions of stored data objects. The compute node is configured to receive a query and generate a transaction context (TC) and modified table schemas (MTS) scoped to the query, and pushdown the query, TC and MTS to the page server that is configured to determine which data objects at the page server satisfy the query, and for each such object, which version of the object should be returned based on the TC.

  • Publication number: 20220197911
    Abstract: Methods for operation fragmentation with metadata serialization in query processing pushdowns are performed by systems and devices. A compute node receives a query directed to database data, and generates query text fragments. Portions of metadata of the database are read from different page servers, and are serialized by the compute node. Page identities of data pages in a page server that stores the data are determined from a page index at the compute node, and the compute node provides the text fragments, the serialized metadata, and the page identities to the page server storing the data. The page server compiles the text fragments based on the serialized metadata to generate an executable query plan for the query. The page server initializes and performs execution of the executable query plan against the data as a pushdown query operation, and a result of pushdown query operation is provided to the compute node.

  • Patent number: 11276382
    Abstract: A vehicle sound absorber system includes a sound absorber fixing fastener having a cap with a cylindrical bore and an end face including multiple flexible bite members. A sound absorber material body is locally compressed and partially captured within the cylindrical bore. A remainder of the sound absorber material body not captured within the cylindrical bore extends radially outward and freely away from the cap. A stud extending from a vehicle body wall extends through a through aperture created in the sound absorber material body and a sound absorber panel of an acoustic material mounted on the vehicle body wall. The cap is captured on the stud by frictional engagement of the flexible bite members on the stud. The sound absorbing material of the sound absorber material body replaces sound absorber material removed to form each of a recessed area and a fully compressed layer of the sound absorber panel.

  • Patent number: 11249866
    Abstract: Embodiments described herein detect data corruption in a distributed data set system. For example, a system comprises node(s) for processing queries with respect to a distributed data set comprising a plurality of storage segments. A write transaction resulting from a query with respect to a particular storage segment is logged in a log record that describes a modification to the storage segment. A log service provides the log record to a data server managing a portion of the distributed data set in which the storage segment is included, which performs the write transaction with respect to the storage segment. For redundancy purposes, the data server has replica(s) that manage respective replicas of the portion of the distributed data set managed thereby. For backup purposes, snapshots of the replica(s) are periodically generated. To determine a data corruption, a snapshot of one replica is cross-validated with a snapshot of another replica.

  • Patent number: 11151101
    Abstract: Adaptive adjusting of the growth of a persistent log. The persistent log has a log record generator that adds log records to the persistent log. In addition, there are multiple log consumers that consume records from the persistent log. The log consumers publish log processing parameters with respect to the persistent log. The log processing parameters are then used to determine an appropriate adjustment in the growth of the log, which adjustments may then be executed. As an example, the log processing parameter may be a log consumption progress, in which case the log generator may be caused to slow down the generation of log records, thereby slowing the growth of the log.

  • Patent number: 11048664
    Abstract: The bifurcation of a log into a fixed-size log portion and a growable log portion. Log records are first written to the fixed-size log portion. At some point, the older log records within the fixed-size log portion are destaged to the growable log portion. Destaging may involve copying the log records from the fixed-size log portion and tacking the log record onto the end of the growable log portion. This destaging might occur one sub-portion (e.g., one virtual log file) at a time. The more recent log records are within the fixed-size log portion. Accordingly, new writes to the log occur to the fixed-size log portion. Furthermore, a large portion of the reads are of the more recent log records within the fixed-size log portion. Thus, optimizing performance within the fixed-size log portion results in significant improvement in the performance of the overall log.

  • Patent number: 10949412
    Abstract: The use of log marking (otherwise known as “coloring”) of sub-portions of a log that records actions (e.g., data operations) performed by a computing system. The log is composed of multiple sub-portions, such as virtual log files, which are successively added to the log as the log grows. For instance, the sub-portions may be virtual log files of the log. The principles described herein change the use of log marking depending on which sub-portion of the log is being marked. If the computing system fails, and recovery is needed, the recovery process can thus deterministically identify where the last written log record is.
