Overview
Introducing Hydra, a GraphQL query node for substrate chains
Bird-eye overview
Hydra has two principal components: Hydra Indexer and Hydra Processor. Hydra Indexer ingests raw data from a substrate chain. Hydra Processor is responsible for transforming the raw data into domain-level entities as defined in schema.graphl and the event handlers, both provided by the user. hydra-cli provides additional scaffolding and codegen tooling for running and developing a Hydra Processor tailored for the provided schema file.
