+are performed on a temporary table using the sequence of operations described in [SQLite official documentation](https://www.sqlite.org/lang_altertable.html#otheralter).
+
+## Gremlin
+
+Gremlin does not support migration nor indexes, and **<ins>it's considered experimental</ins>**.
+
+## TiDB **(<ins>preview</ins>)**
+
+TiDB support is in preview and requires the [Atlas migration engine](migrate.md#atlas-integration).  
+TiDB is MySQL compatible and thus any feature that works on MySQL _should_ work on TiDB as well.  
+For a list of known compatibility issues, visit: https://docs.pingcap.com/tidb/stable/mysql-compatibility  
+The integration with TiDB is currently tested on versions `5.4.0`, `6.0.0`.
