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.

Database processing method and apparatus, and computer-readable storage medium

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.

Method and apparatus for realizing globally unique index

A service request message sending method, a distributed database architecture and a computer readable storage medium are disclosed. The method includes: receiving (S) a service request message, and sending (S) the service request message to a corresponding storage unit through N tiers of computing nodes, where N is an integer greater than or equal to 2, and the closer the tier is to the storage unit, the larger the number of computing nodes in that tier is.
