Abstract

The embodiment of the invention provides an index creation method and device, electronic equipment and a storage medium, and relates to the technical field of databases. The method comprises the stepsof obtaining a database index creation statement, and writing the database index creation statement into a first system table; writing the database index creation statement into the first log file, and sending log information corresponding to the database index creation statement in the first log file to a slave library so that the slave library plays back the log information; and reading the database index creation statement from the first system table, and executing the database index creation statement. According to the invention, the time for a master library and a slave library to integrally complete index creation can be shortened.
