Architecture Overview‚Äč

In general stellar-etl runs by:

  • Read raw data from the Stellar network
  • This can be done by running a stellar-etl export command to export data between a start and end ledger
    • stellar-etl has the ability to read from two different sources:
      • Captive-core directly to get LedgerCloseMeta
      • A data lake of compressed LedgerCloseMeta files from Ledger Exporter
  • Tranforms the LedgerCloseMeta XDR into an easy to parse JSON format
  • Optionally uploads the JSON files to GCS or any other cloud storage service

More detailed information about stellar-etl and examples can be found in the stellar-etl repo.
