/**
 * This implementation uses a {@link DriverManagerDataSource} and {@link DefaultTransactionDefinition}. It suspends the existing transaction and purposely
 * runs this logic in "no transaction" to ensure we don't create a connection that would potentially become idle while all JDBC tasks execute. If the
 * underlying connection pool has an abandoned connection timeout, it would reclaim and close the connection. Then when all the JDBC tasks below finish,
 * this transaction would try to commit and would generate a "commit failed" exception because the connection is already closed. This approach is fine since
 * we are not actually doing any "herd" DB operations below. When all the below JDBC operations are finished, nothing would happen here except the callers
 * transaction would pick up where it left off which would be needed to write workflow variables, etc.
