There was a problem hiding this comment.
Maybe for a follow-up PR; I think that this will always return false, as we are parsing the string spanner.enable_direct_access as a boolean. Something similar was also true before this change, so I don't think we are breaking anything, but I doubt that this does what is intended to do.

Yes. We should do System.getProperty. I will raise a separate PR to fix this.

Description:
Directpath allows GCP VM to connect to Spanner directly instead of going through public Google frontend. It improves the performance of the client library since all the requests are directly flowing to Spanner directly.
If client workload is deployed in non GCP VM, directpath will not work. it will fallback to connecting to Google public frondend.
In JDBC, we will be providing the support where customers can add the property enableDirectAccess=true which will enable directpath for the connection.
