In the InnoDB storage engine's data dictionary, each table is associated with a tablespace; these tablespace files are stored in the data directory. The temporary tablespace defines a shared memory region for each InnoDB storage engine instance within a database.ibtmp1 The file is typically located in the MySQL data directory; its size dynamically grows or shrinks depending on the usage of the temporary tablespace. If it is necessary to recreate a tablespace that was accidentally deleted by InnoDB,ibtmp1 The document will be used as a template.
