You can find detailed documentation at docs.rarible.org.

For reading NFT events, we need to add Subscriber (see com.rarible.flow.scanner.subscriber package) with the event's description (usually contract name and event name) and start block height.
The service uses Kafka to exchange messages with other Rarible services.
The service also uses MongoDB as a persistence storage.

| blockchain.scanner.flow.chainId | Flow network for indexing (MAINNET, TESTNET, EMULATOR) |
