In [M2 dev docs][1] there is this regarding auto increment:

> identity	Indicates whether a column is auto incremented.

Here's excerpt from my db_schema.xml:
    

    <column xsi:type="int" name="entity_id" padding="11" unsigned="false" nullable="false" identity="true" comment="Entity ID"/>

No AUTO_INCREMENT in db is found. What am I doing wrong/missing?

Magento 2.3.4, MySQL 5.7

UPD. It seems like db_schema is cached somewhere. Nothing I do affects it, nor changing padding, nor anything else. 

UPD2. Adding a column works. Moreso, even commenting old entity_id column and adding a dummy column with auto_increment works.
