This feature adds the functionality of ignorability for indexes. Indexes are not ignored be default. To control index ignorability explicitly for a new index, use IGNORE or NOT IGNORE as part of the index definition for CREATE TABLE, CREATE INDEX, or ALTER TABLE. Primary keys (explicit or implicit) cannot be made ignorable. The table INFORMATION_SCHEMA.STATISTICS get a new column named IGNORED that would store whether an index needs to be ignored or not.
