I’m using the JavaScript gRPC client, and I’m familiar with the [example](https://github.com/dgraph-io/dgraph-js#altering-the-database) for altering the database…

```auto
const schema = "name: string @index(exact) .";
const op = new dgraph.Operation();
op.setSchema(schema);
await dgraphClient.alter(op);

```

…but is it possible to modify the schema in a transaction, so I can abort if needed and not have any schema changes take effect?

Nope, as far as I know. Alter Schema is an operation.
