Initializing a cloud BigTable instance

Once you've created a BigTable instance and a Service Account key, these Go scripts can create the table and column families to save event data.

Pass your BigTable connection info via args:

• the Google Cloud projectID
• BigTable instance name
• the path to a GCP Service Account with appropriate permissions

Invoke the script with the DB config options and -setupDB to create the table and column families, if they do not already exist. If they do already exists when the script runs, it will do nothing.

go run . \
  -project your-GCP-projectID \
  -instance your-BigTable-instance-name \
  -keyFilePath ./service-account-key.json \
  -setupDB

Querying cloud BigTable

Lookup a row by the EmitterChain:TxID:

go run . \
  -project wormhole-315720 \
  -instance wormhole \
  -keyFilePath ./bigtable-admin.json \
  -queryRowKey 2:000000000000000000000000e982e462b094850f12af94d21d470e21be9d0e9:6

Lookup all rows with a timestamp >= queryPreviousMinutes ago:

go run . \
  -project wormhole-315720 \
  -instance wormhole \
  -keyFilePath ./bigtable-admin.json \
  -queryPreviousMinutes 120
