I want to perform units of work in a single transaction using Google spanner template,

spannerTemplate.performReadWriteTransaction(trasac -> {
  // Write in table 1
  // Write in table 2   
});

Am getting exception as 'Nested transactions are not supported', please help me on this.

Maybe this could help: I had @Transactional annotations on service methods that called performReadWriteTransaction method, so I removed that annotation. As stated here such methods "cannot be used in @Transactional annotated methods because Cloud Spanner does not support transactions within transactions."

As per the change described here nested transactions are blocked by default on Spanner Client libraries.

To override this behavior you can call TransactionRunner.allowNestedTransaction() instead.
