The dag should run daily and query the last day's partition, save it to a temporary table and extract the result to a GCS bucket in gzipped csvs. The following tables should be exported:

  • blocks
  • transactions
  • traces
  • logs
  • token_transfers
  • contracts

The dag should have sensor to wait for checkpoint file in GCS, which is implemented here https://github.com/blockchain-etl/ethereum-etl-airflow/pull/142/files.
