The embodiment of the application provides a commissioning and rollback method and system for a communication system configuration, comprising: loading a current effective configuration in a front-end workstation, generating an incremental snapshot in response to an input incremental change instruction; generating a virtual production configuration based on the incremental snapshot and the current effective configuration; generating and outputting a trajectory log based on the virtual production configuration and simulation input parameters; performing configuration mapping on the trajectory log to obtain configuration rule hit information; performing commissioning and pre-checking based on the configuration rule hit information, generating and outputting risk information; generating a commissioning passing instruction through the risk information, and submitting the incremental snapshot to a back-end; when detecting that abnormal information appears in a database transaction, performing a reverse patch to realize atomic rollback; and connecting each incremental change instruction and the reverse patch to a configuration version tree to preview the configuration of any historical node. The method realizes atomic submission and accurate rollback, and can quickly restore the system to an accurate state before the change.

The application discloses a kind of physical view incremental refreshing method, device, equipment, medium and product, it is related to database technical field.The method comprises: dividing base table, obtains at least two sub-tables of shard;Log temporary table and log main table of physical view are created for the sub-table of shard;In data shard, shard local physical view is created, and incremental refreshing control information is registered;According to incremental refreshing point, the log temporary table and the log main table determine incremental change set;According to the base table involved in the shard local physical view and the incremental change set, the shard local physical view is refreshed, obtains the new shard local physical view or intermediate result set of the sub-table of shard;At least two new shard local physical views or intermediate result sets of sub-table of shard are merged, and the target physical view of the base table is obtained.
