Cloud Run Cold Starts to Datastore Take Tens of Seconds #481
Description
This is a similar issue to here, except slower: #9
To reproduce the problem I used @JustinBeckwith 's code from here #9 (comment) as a template.
Environment details
- OS: Cloud Run (hosted)
- Node.js version: 12.9.0
- npm version: 6.10.2
@google-cloud/datastoreversion: 4.2.0
Steps to reproduce
- Setup Datastore in a gcp project (creating a test entity is optional)
- Setup Cloud Run in a gcp project (you can use this to build a docker image: https://github.com/chrishiestand/cloud-run-datastore-latency-test )
A. Be sure to populate the env vars KIND and ID
B. The Cloud Run service account must have datastore access, so add permissions if necessary - Hit the Cloud Run URL in your browser e.g. https://cloud-run-test-xyz-ue.a.run.app/
Look at the getTime that is returned, for me, it is waaay too slow on cold start (ranges from ~15-40 seconds). Warmed containers answer in a reasonable amount of time e.g. ~20-50 milliseconds.
Thanks!
