Re: [google-cloud-sql-discuss] Re: Cloud Functions -> Cloud SQL via Socket Factory too slow

Hi Hans,

I was just able to confirm this was an oversight on my part that only effects the postgres module. I've opened a PR to address it (#146).

Thanks,
Kurtis

Hi, Kurtis

Thanks for the fix. I just tested it. It now automatically uses the unix socket as expected but I'm still seeing it log "INFO: First Cloud SQL connection, generating RSA key pair". During my run, generating the key pair took ~3 seconds, so still slow. I was under the impression that that step would be skipped? But I certainly don't know enough about what goes on behind the scenes there to claim that it should be skipped.

Another minor thing, the readme at https://github.com/GoogleCloudPlatform/cloud-sql-jdbc-socket-factory could probably be updated to include a mention for Functions, so something like...

"The library will automatically detect when it is running on GAE Standard and Cloud Functions, and will connect via the provided unix socket for reduced latency."

Hi Hans,

We released v1.0.14 of the Cloud SQL JDBC Socket Factory today. It contains several performance improvements, including some improvements for functions. Please give it a try and let me know how it goes.

Thanks,

Kurtis

Hello Hans,

It seems that Kurtis has submitted an open issue on your behalf for this in the 'cloud-sql-jdbc-socket-factory' GitHub repository. I'd suggest to add any relevant information and findings you might have gathered from your specific use cases in that thread as well.

Hi, Kurtis

Thanks for the suggestion. I did try that on Friday, and even though the log showed the setting took effect, it didn't change things for the better.

Hey Hans,

That is much higher latency than I would expect to see with the socket factory. 

In the meantime, you can try setting the env var `CLOUD_SQL_FORCE_UNIX_SOCKET=true` to see if that improves the situation. This takes advantage of the `/clousql` unix socket that is provided to functions environments. 

Please let me know if that works for you.

Thanks,

Kurtis

So I'm connecting from Cloud Functions for Java in us-central1 to Cloud SQL (postgres 11) in us-west1 using the socket factory approach ('com.google.cloud.sql:postgres-socket-factory:1.0.13'). Everything works, but it takes around ~10 seconds to first obtain the connection, which is the problem. I am spanning two locations, but I didn't think it'd make that much of a difference. Here are the key log entries and the amount of time each one takes. Is this inline with what everyone else is seeing too? I haven't tried creating my own client cert yet but was hoping to avoid managing that.

• 6 ms:  INFO: Connecting to Cloud SQL instance [projectid:us-west1:instancename] via SSL socket.
• 7 sec: INFO: First Cloud SQL connection, generating RSA key pair
• 3 sec: INFO: Obtaining ephemeral certificate for Cloud SQL instance [projectid:us-west1:instancename]...
• 1 sec: INFO: Connecting to Cloud SQL instance [projectid:us-west1:instancename] on IP [public ip].

Any insight appreciated.

Hans
