Whats the best way to access Memorystore from Local Machines during development? Is there something like Cloud SQL Proxy that I can use to set up a tunnel?
Memorystore does not allow connecting from local machines, other ways like from CE, GAE are expensive especially your project is small or in developing phase, I suggest you create a cloud function to execute memorystore, it's serverless service which means lower fee to execute. I wrote small tool for this, the result is similar to run on local machine. You can check if help to you.
