Data aggregator

The data aggregator scans blocks near real time as they are produced by the blockchain.

The scan results are per transaction processed by different associated handlers.

Start parameters

The data aggregator can be started with the following parameters:

• NETWORKS : Network config JSON similar to "{\"Node\": [{\"Network\": \"devnet\",\"GRPCHost\": \"full-node.devnet-1.coreum.dev:9090\",\"RPCHost\": \"https://full-node.devnet-1.coreum.dev:26657\"}]}",`
• STATE_STORE - Store connection host:port format
• TRADE_STORE - Store connection host:port format
• OHLC_STORE - Store connection host:port format
• ORDER_STORE - Store connection host:port format
• CURRENCY_STORE - Store connection host:port format
• LOG_LEVEL - Optional

NETWORKS

The NETWORKS env is a JSON that can hold one or more Coreum nodes, 1 per network. In most user facing applications the users will only use mainnet however for development and testing purposes you can add devnet and testnet nodes.

Sample:

{
    "Node": [
        {
            "Network": "devnet",
            "GRPCHost": "full-node.devnet-1.coreum.dev:9090",
            "RPCHost": "https://full-node.devnet-1.coreum.dev:26657"
        }
    ]
}

The use of this style of configuration allows operations to be connected to either a public node (not recommended for production) or a private node (recommended for production).
