As a result `MyEntity.drafts` is created in the database.

:::warning Warning: Known Limitation!
Due to an implementation detail of the [`hdb` HANA driver](https://www.npmjs.com/package/hdb), trying to `INSERT` draft entities with fields that use the [`LargeBinary` type](https://cap.cloud.sap/docs/cds/types#core-built-in-types) will cause a deadlock.
Unfortunately, the only currently known workaround is to [configure your CAP app](../guides/databases/hana#setup-configuration) to use the [`hana-client` HANA driver](https://www.npmjs.com/package/@sap/hana-client) instead.
