  • Instance-based distributed data recovery method and apparatus
    Patent number: 10783163
    Abstract: The present application discloses an instance-based distributed data recovery method. A specific implementation of the method includes: detecting a non-master down node; allocating multiple secondary storage units corresponding to the down node to at least one online node; performing hash grouping on instances stored on logs and allocating the instances to multiple threads; and recovering data of multiple primary storage units in parallel inside the online node. Embodiments of the present invention recover data of a down node in a distributed database in parallel in nodes.

  • Method and apparatus for storing time series data
    Patent number: 10606806
    Abstract: A method and apparatus for storing time series data are disclosed. A method may include: saving an index value of time series data to a time interval data table according to a time point of the time series data, wherein the time series data includes: a time point and an index value associated with the time point, and each data row in the time interval data table records index values associated with at least one time point within a time interval of a predetermined length; performing data compression processing on a storage area having no written data, to obtain compressed time interval data; and writing the compressed time interval data to a magnetic disk.
