Subgraph Manifest Definition
A Subgraph Manifest is a critical component of the Graph Protocol, a decentralized indexing protocol for blockchain data. It is essentially a YAML file that outlines how to ingest, index, and serve blockchain data in a structured and efficient manner. The Subgraph Manifest specifies the smart contracts of interest on the Ethereum blockchain, the events in those contracts to pay attention to, and how to map event data to data that The Graph will store in its hosted service.
Subgraph Manifest Key Points
- A Subgraph Manifest is a YAML file that defines how to index and serve blockchain data.
- It is a part of The Graph Protocol, a decentralized indexing protocol for blockchain data.
- The Subgraph Manifest specifies the smart contracts to monitor on the Ethereum blockchain and the events in those contracts to track.
- It also defines how to map event data to data that The Graph will store in its hosted service.
What is a Subgraph Manifest?
A Subgraph Manifest is a crucial element in the Graph Protocol’s operation. The Graph Protocol is a decentralized and open-source indexing protocol for blockchain data. This protocol allows developers to efficiently access blockchain data by creating and publishing different ‘subgraphs’ that define how to ingest and index blockchain data. The Subgraph Manifest is the YAML file that outlines these instructions.
Why is a Subgraph Manifest important?
The Subgraph Manifest is important because it allows for efficient and structured access to blockchain data. Without it, developers would have to manually sift through raw blockchain data, which can be time-consuming and inefficient. By specifying the smart contracts and events to track, the Subgraph Manifest allows developers to focus only on the data that is relevant to their application or service.
Where is a Subgraph Manifest used?
A Subgraph Manifest is used in the Graph Protocol, specifically in the creation and publishing of ‘subgraphs’. These subgraphs are essentially APIs that allow developers to access indexed blockchain data. The Subgraph Manifest is the file that defines how these subgraphs should ingest, index, and serve blockchain data.
When is a Subgraph Manifest used?
A Subgraph Manifest is used whenever a new subgraph is created or an existing one is updated. It is the blueprint that guides how the subgraph should operate, so it is essential whenever changes are made to the subgraph’s operation.
How does a Subgraph Manifest work?
A Subgraph Manifest works by providing clear instructions on how to handle blockchain data. It specifies the smart contracts to monitor on the Ethereum blockchain, the events in those contracts to pay attention to, and how to map event data to data that The Graph will store in its hosted service. This allows the subgraph to efficiently and accurately index and serve blockchain data.
