## Op Templates
The Google Cloud Spanner adapter supports the following operations:
+
+* `create_database_ddl` - Data Definition Language operations such as creating and dropping databases.
* `update_database_ddl` - Data Definition Language operations such as creating and dropping tables, indexes, etc.
* `execute_dml` - Data Manipulation Language operations. Read only operations are supported at this time, including queries
and vector queries.
* `insert` - Insert a single record, vector or non-vector, of data into the database.
