2. What did you expect to see?
This DDL should run successfully.

```sql
ALTER TABLE `django_content_type` ADD CONSTRAINT `django_content_type_app_label_model_76bd3d3b_uniq` UNIQUE (`app_label`, `model`);

  1. What did you see instead? It gets ERROR 8256 (HY000): Check ingest environment failed: no enough space in /tmp/tidb/tmp_ddl-4000.
