  • Method and apparatus for job operation retry
    Patent number: 10866862
    Abstract: Embodiments of the present application provide operation retry methods and apparatuses. One exemplary method includes: detecting whether an operation of a job fails; if there is an operation failure, collecting statistics on a progress of the job; calculating a retry interval according to the progress of the job; and re-executing the operation after waiting for the retry interval. When an operation of a job fails, the retry interval can be adaptively calculated according to the progress of the job. This can help increase the length of the retry interval, especially for a long job. The job can thereby be retried dynamically, to cope with longer service interruption. Embodiments of the present application can help avoid waste of resource waste caused by job failure and job re-execution, and reduce the retry costs while ensuring the success rate of the job.

  • Mirror vote synchronization
    Patent number: 10852984
    Abstract: One or more techniques and/or systems are provided for mirror vote synchronization. For example, a first storage device is located at a first storage site, and a second storage device is located at a second storage site. The second storage device is configured according to a data mirroring configuration where data from the first storage device is mirrored to the second storage device. Mirror vote metadata is generated based upon an up-to-date state of the data mirroring configuration. The mirror vote metadata indicates whether the first storage device and/or the second storage device are up-to-date or not. The mirror vote metadata may be replicated between the first storage site and the second storage site. If the first storage site fails, then the second storage site may provide switchover operation using the second storage device based upon the mirror vote metadata.

  • Data tuple testing and routing for a streaming application
    Patent number: 10838800
    Abstract: A tuple testing and routing operator in a streaming application routes data tuples to multiple parallel test operators that test in parallel the data tuples, receives feedback from the multiple parallel test operators regarding the results of testing the data tuples, routes a data tuple to a first operator when the data tuple passes the multiple parallel test operators according to a specified pass threshold, and optionally routes the data tuple to a second operator when the data tuple does not pass the multiple parallel test operators according to the specified pass threshold. The pass threshold allows testing to be done in a way that does not require all tests to be performed for all data tuples, thereby enhancing performance.

  • Managing read and write requests targeting a failed storage region in a storage system
    Patent number: 10838834
    Abstract: A system and method for efficiently distributing data among multiple storage devices. A data storage array receives read and write requests from multiple client computers. The data storage array includes multiple storage devices, each with multiple allocation units (AUs). A storage controller within the data storage array determines a RAID layout for use in storing data. In response to determining a failure of a first AU, the storage controller begins reconstructing in a second AU the data stored in the first AU. For read and write requests targeting data in the first AU, the request is serviced by the first AU responsive to determining no error occurs when accessing the first AU.
