  • Patent number: 10922303
    Abstract: A system that implements a data storage system may store data for a database table in multiple replicated partitions on respective storage nodes. An export of an active database partition may generate an exported copy of the database partition. A first exported copy may be stored locally on a source node and a second exported copy of the database partition may be sent to a recipient node. The source node may validate the first copy responsive to sending the second copy and may perform the validation while the second copy is being sent and processed at the recipient node. If the first copy cannot be validated, the source node may cause the second copy to be invalidated and abort further processing of the second copy. The source node may also cause the second copy to be marked as invalid to prevent reliance on an invalid database partition copy.

  • Patent number: 10747739
    Abstract: A data storage system may implement implicit checkpoint for generating a secondary of a table. Indexing updates may be replicated and maintained across a replica group storing a table for a data store. Upon detection of a restart event for generating a secondary index, a replica in the replica group may evaluate the indexing updates to determine an index creation restart point according to an order for indexing the table. The generation of the secondary index may be resumed at the index creation restart point. In this way, secondary index generation may continue whether or not a previously indexing replica in the replica group, such as a master replica, is available to continue generating the secondary index.

  • Patent number: 10715479
    Abstract: Methods and apparatus for connection redistribution in load-balanced systems that include multiple load balancers each serving multiple nodes. In the connection redistribution method, each node estimates a connection close rate, which may be based on an estimation of the percentage of the overall client traffic received by the respective load balancer that is being handled by the node. The node generates close requests for connections between the respective load balancer and clients according to the connection close rate. The node sends the close requests to its load balancer, which forwards the close requests to the appropriate clients. Upon receiving a close request, a client may close the connection(s) indicated by the request, obtain a public IP address for a load balancer, and initiate new connection(s) to the respective load balancer via the public IP address.

  • Publication number: 20200145784
    Abstract: Apparatus and methods for provision of location-based services to wireless device users. In one embodiment, the apparatus and methods support location-based services requiring indoors or underground positioning (or other applications which cannot be served by GPS/A-GPS or GLONASS), such as via Wi-Fi Location devices with fine timing measurement (FTM) capability. A cable, terrestrial or satellite network operator can obtain location data on e.g., an LTE-enabled UE with SIM capability located within a served premises or venue, via an HTTP/S GET protocol, and forward the location data. In one variant, a managed 3 GPP IP Multimedia System (IMS) infrastructure is used in conjunction with UE-specific identifiers under control of a controller entity (e.g., ePDG) in communication with the IMS infrastructure and one or more FTM-enabled Wi-Fi APs within the premises or venue for supporting VoWi-Fi 911 or 411 packet calls made via the IMS.

  • Patent number: 10459898
    Abstract: Methods and apparatus for configurable-capacity time-series tables are disclosed. A schedule of database table management operations, including at least an operation to change a throughput constraint associated with a table in response to a triggering event, is generated. The table is instantiated with an initial throughput constraint in accordance with the schedule. Work requests directed to the table are accepted based on the initial throughput constraint. The throughput constraint is modified in response to the triggering event. Subsequent work requests are accepted based on the modified throughput constraint.

  • Patent number: 10135703
    Abstract: A data storage system may implement generating creation performance metrics for a secondary index of a table. Metrics may be collected from different partitions of a table and different partitions of a secondary index in a table store upon initiating creation of the secondary index for the table that utilize provisioned resources for creating the secondary index. The metrics may be analyzed to generate performance metrics for the creation of the table. The performance metrics may be provided to clients of the data store or to monitoring systems. Monitoring systems may send performance event notifications to clients or automatically perform modifications to the provisioned throughput capacity.

  • Patent number: 10102230
    Abstract: A data storage system may implement rate-limiting secondary index creation for an online table. A secondary index may be generated for a table stored in a data store. The table may be incrementally indexed, maintaining the updates determined according to indexing different portions of the table in a queue of pending updates that are subsequently applied at the secondary index. Prior to indexing a portion of the table, an evaluation of a current number of pending updates in the queue of pending updates may be performed with respect to a throttle threshold. If the current number of pending updates exceeds the throttle threshold, then indexing the portion of the table may be throttled. Received updates to previously indexed portions of the table, may be applied to the table and placed in the queue of pending updates without an evaluation of the current number of pending requests.

  • Patent number: 10013449
    Abstract: A non-relational data store may implement validating and non-validating secondary indexes for a table. Operations at a table for a given item may be performed when indexing the item to create a secondary index or when updates to the given item are received. Attribute values of a given item may be validated with respect to an indexing schema for the secondary index. For a non-validating secondary index, validation errors detected for the attribute values may be ignored so that the operation at the table may be performed. For a validating secondary index, validation errors detected for the attribute values may result in denying performance of the operation. In some embodiments, a secondary index from may be changed from validating to non-validating, or non-validating to validating.

  • Patent number: 9875270
    Abstract: A data storage system may implement locking item ranges for creating a secondary index of an online table. A secondary index may be generated for a table of items stored in a non-relational data store. Different ranges of items in the data store may be locked while a corresponding portion of the secondary index is generated. Upon generating the corresponding portion of the secondary index, a range of items may be unlocked. While generating the secondary index, the table may be made available for servicing access requests. For a request to update the table received during the generation of the secondary index, a determination may be made as to whether the update is included within a locked range of the table. If locked, the request may be delayed until the range is unlocked.
