Abstract: This application discloses a time series data management method, device, and apparatus. A device receives a data query request, wherein the data query request includes an identifier of the first object. The device obtains first time series data corresponding to the first object in a target data table according to the identifier of the first object. The device determines a second storage location that is in a location index table and that is stored in a first storage location corresponding to the first object. Further, the device obtains second time series data of the first object and a third storage location corresponding to the second time series data that are stored in the second storage location, The device also obtains other time series data corresponding to the first object according to the third storage location.

Abstract: Embodiments of the present invention provide a method and an apparatus for concurrent access of mixed services, and relate to the field of database applications, so as to implement concurrent read/write access to a database service, allow lock-free concurrency of query and modification operations, lower operation complexity, reduce overheads, reduce a waste of memory, and improve data timeliness. The method includes: dividing a data table to obtain at least one data set; breaking down a modification or query operation on the data table into at least one point operation; determining whether to-be-processed data on which point operation processing is performed is distributed in multiple columns; and if the to-be-processed data is distributed in multiple columns, determining whether the to-be-processed data is in a same data set, and performing a modification or query operation on the to-be-processed data according to a result of the determining.
