+### <a id="sidecardb-issue"/>VTTablet runs an unnecessary DDL
+In this release, with MySQL 8.0 whenever VTTablet's tabletserver goes through initialization, it finds
+a diff in its internal `schemacopy` table and tries to apply a DDL to fix it. The DDL
+is a no-op and this loop of applying the DDL continues to run.
+
+If this problem is encountered, the following PR should be reverted to resolve it - https://github.com/vitessio/vitess/pull/15859.
