Before you can run anything, you must change the TSUNAMI_API_KEY constant in src/datalake.ts to your private Tsunami key.
src/datalake.ts implements a very simple stateful datalake monitoring the CNS Registry contract on Ethereum mainnet. The code is annotated to help you modify it for your purposes.
To build the runner image:
sudo docker build -t datalake-template-dev .
To run:
sudo docker-compose up
The datalake is currently configured to reset its state on each run. To change that behavior, as well as other configuration details, take a look at docker-compose.yml.
You can inspect the current state of the datalake using:
psql postgresql://datalake:datalake@localhost:54329/datalake
The domains_entities table contains mappings of token IDs to names, and the ownership_entities table tracks the current token ownership. The tables with names ending in _mutations contain historical data.
After running npm install you can find the README file for the datalake SDK at node_modules/@parsiq/datalake-sdk/README.md.
Have fun!
