Abstract: Provided are a database processing method and apparatus, and a computer readable storage medium. The database processing method comprises: after a lock wait is generated, writing lock wait related information into a lock wait log.

Abstract: Disclosed in embodiments of the present disclosure are methods and apparatuses for realizing a globally unique index, which are applicable to a distributed database. One of the methods includes: receiving a structured query language, SQL, request, obtaining a conflict detection SQL statement corresponding to the SQL request and calculating an expected value; issuing the conflict detection SQL statement to each database node for execution; obtaining an execution result of the conflict detection SQL statement, and comparing the execution result of the conflict detection SQL statement with the expected value; and when the execution result of the conflict detection SQL statement is less than or equal to the expected value, processing an original SQL statement of the SQL request, and issuing the original SQL statement to the each database node for execution.

Abstract: Embodiments of the present disclosure relate to the technical field of cloud computing, and provide a method and an apparatus for implementing a video conference, an electronic device and a computer-readable storage medium. The method for implementing a video conference includes: acquiring video conference main window information in video conference window information, where the video conference window information includes the video conference main window information and video conference auxiliary window information; and synchronously displaying the video conference main window information and the video conference auxiliary window information, where the video conference auxiliary window information is displayed at a cloud desktop server.
