             Summary: Drop column does not remove column from internal schema
                 Key: IGNITE-11604
                 URL: https://issues.apache.org/jira/browse/IGNITE-11604
             Project: Ignite
          Issue Type: Bug
            Reporter: Alexey Goncharuk


Discovered this during the work on IGNITE-11541 (see {{StaticCacheDdlTest.testDropColumn}}).

After a quick debug I see the following: in {{GridQueryProcessor#onSchemaFinishDiscovery}} we call {{DynamicCacheDescriptor.schemaChangeFinish(msg)}}, which eventually calls {{QuerySchema.finish(op)}}.
Inside that method we have the following: the {{message.columns()}} collection has the field name in upper case (in the test it's "FIELD_TO_DROP"), but the entity's fields map contains lower-case names ("field_to_drop"). As a result, we do not remove the field from the query entity, this query entity is saved to the stored cache data and field re-appears after restart.
