> If schema evolution behavior is set to LENIENT, Truncate / Drop table events will be ignored by default. However, there's currently no way for users to override this behavior due to the following code:
> ```java
> if (excludedSETypes.isEmpty()
> && SchemaChangeBehavior.LENIENT.equals(schemaChangeBehavior)) {
> // In lenient mode, we exclude DROP_TABLE and TRUNCATE_TABLE by default. This could be
> // overridden by manually specifying excluded types.
> Stream.of(SchemaChangeEventType.DROP_TABLE, SchemaChangeEventType.TRUNCATE_TABLE)
> .map(SchemaChangeEventType::getTag)
> .forEach(excludedSETypes::add);
> }
> ```
>  
> If one wants to exclude no types, it's actually not possible since passing `[]` is equivalent to passing nothing, and `DROP` and `TRUNCATE` events will still be ignored.
