Embodiments of the present disclosure disclose a data processing method, apparatus, and system. The method provided in the embodiments of the present disclosure includes receiving a data processing request sent by a client and obtaining a routing table according to the data processing request. The routing table stores structure information of a relational database. The relational database includes a plurality of sub-databases. The sub-database includes a plurality of partitioned tables, and the partitioned table includes a plurality of shards. The method also includes determining a target sub-database according to the data processing request and the routing table. The method further includes sending the data processing request to the target sub-database, so that the target sub-database performs an operation according to the data processing request.

Data processing method, apparatus, system, and storage medium

A method for forming deformation crystal twins in piezoelectric materials is disclosed. The method includes obtaining a crystalline piezoelectric material and deforming the crystalline piezoelectric material using a load. The method also includes heating the deformed crystalline piezoelectric material in an oxidative atmosphere to a predetermined temperature for a predetermined time to form a plurality of deformation crystal twins in the crystalline piezoelectric material. The method also includes allowing the crystalline piezoelectric material to cool to room temperature, and removing the load that induces the deformation of the crystalline piezoelectric material. Additionally, the deformation of the crystalline piezoelectric material is achieved by at least one of the following: compressing, stretching, shearing, torsion, and bending of the crystalline piezoelectric material. Further, the shearing creates a shear plane that acts as a twin boundary, which separates a plurality of deformation crystal twins with non-uniform orientation.
