README.md

Google Cloud function for reading BigTable

This is a reference implementaion for getting data out of BigTable.

deploying

First deploy (creation) must include all the flags to configure the environment:

gcloud functions --project your-project deploy testnet --region europe-west3 --entry-point Entry --runtime go116 --trigger-http --allow-unauthenticated --service-account=your-readonly@your-project.iam.gserviceaccount.com --update-env-vars GCP_PROJECT=your-project,BIGTABLE_INSTANCE=wormhole-testnet

gcloud functions --project your-project deploy processvaa-testnet --region europe-west3 --entry-point ProcessVAA --runtime go116 --trigger-topic new-vaa-testnet --service-account=your-readonly@your-project.iam.gserviceaccount.com --update-env-vars GCP_PROJECT=your-project,BIGTABLE_INSTANCE=wormhole-testnet

Subsequent deploys (updates) only need include flags to indentify the resource for updating: project, region, name.

gcloud functions --project your-project deploy testnet --region europe-west3 --entry-point Entry

gcloud functions --project your-project deploy processvaa-testnet --region europe-west3 --entry-point ProcessVAA

invocation

All routes accept their input(s) as query parameters, or request body. Just two different ways of querying:

GET

curl "https://region-project-id.cloudfunctions.net/testnet/readrow?emitterChain=2&emitterAddress=000000000000000000000000e982e462b094850f12af94d21d470e21be9d0e9c&sequence=0000000000000006"

POST

curl -X POST  https://region-project-id.cloudfunctions.net/testnet/readrow \
-H "Content-Type:application/json" \
-d \
'{"emitterChain":"2", "emitterAddress":"000000000000000000000000e982e462b094850f12af94d21d470e21be9d0e9c", "sequence":"0000000000000006"}'
