After Upgrading to MySQL Server 5.7 or MySQL NDB Cluster 7.5/7.6, mysql_upgrade Takes a Very Long Time Rebuilding Tables with Temporal Columns (Doc ID 2468967.1)

Last updated on MARCH 02, 2020

Applies to:

MySQL Cluster - Version 7.5 to 7.6 [Release 7.5 to 7.0]
MySQL Server - Version 5.7 to 5.7 [Release 5.7]
Information in this document applies to any platform.


After upgrading from MySQL Server 5.6 or earlier to 5.7, the mysql_upgrade script takes a long time to complete due to rebuilding tables with temporal columns. Similar for upgrading MySQL NDB Cluster from version 7.3 or earlier to version 7.5 or 7.6 (the two latter are based on Server 5.7).


MySQL has been upgraded.
