## Initializing 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.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
go run . \
|
||
|
|
-project your-GCP-projectID \
|
||
|
|
-instance your-BigTable-instance-name \
|
||
|
|
-keyFilePath ./service-account-key.json \
|
||
|
|
-setupDB
|
||
|
|
```
|
||
|
|
|
||
|
|
## Querying BigTable
|
||
|
|
|
||
|
|
Lookup a row by the `EmitterChain:TxID`:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
go run . \
|
||
|
|
-project wormhole-315720 \
|
||
|
|
-instance wormhole-dev \
|
||
|
|
-keyFilePath ./bigtable-admin.json \
|
||
|
|
-queryRowKey ethereum:0xf15fe0e6dedef169a25696c577bfddf3d35707210ac641108646d7cfe507f174
|
||
|
|
```
|
||
|
|
|
||
|
|
Lookup all rows with a timestamp >= `queryPreviousMinutes` ago:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
go run . \
|
||
|
|
-project wormhole-315720 \
|
||
|
|
-instance wormhole-dev \
|
||
|
|
-keyFilePath ./bigtable-admin.json \
|
||
|
|
-queryPreviousMinutes 120
|
||
|
|
```
