indexer

Overview ¶

Package indexer implements the runner for the indexer process.

The indexer has two concurrent responsibilities:

1. A processor that streams TokenTransferEvents from the Canton ledger via GetUpdates and persists them (events, token supply, balances) into a dedicated PostgreSQL database.
2. An HTTP read API that exposes the indexed data under /indexer/v1.

Both halves run under the same context via errgroup so that an OS signal or a fatal error in either half cancels the other cleanly.
