METHOD AND APPARATUS FOR CONCURRENT ACCESS OF MIXED SERVICES |
摘要 |
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. |

1. A method for concurrent access of mixed services, comprising:
dividing a data table to obtain at least one data set, wherein each data set comprises at least one column in the data table, and columns in the data set are contiguous; 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. |
