Subgraph Manifest Summary
- A Subgraph Manifest is a configuration file used within The Graph protocol.
- It defines the data sources, entities, and mapping logic for querying blockchain data.
- The manifest is written in YAML format.
- It enables efficient and decentralized data indexing and querying.
- Central to the development and deployment of subgraphs.
Subgraph Manifest Definition
A Subgraph Manifest is a configuration file in YAML format that outlines the data sources, entities, and mapping logic necessary for The Graph protocol to index and query blockchain data efficiently and in a decentralized manner.
What Is Subgraph Manifest?
A Subgraph Manifest is essentially a blueprint for creating a subgraph in The Graph protocol.
It specifies the data sources (typically smart contracts) to be indexed, the blockchain events to watch, and the entities to be created for querying.
This file is crucial for defining how the subgraph will interact with the blockchain data.
Who Uses Subgraph Manifest?
Primarily, developers and data scientists who are working on decentralized applications (dApps) use Subgraph Manifests.
It is also used by those who are building analytics tools that require efficient and scalable blockchain data extraction.
Anyone looking to index blockchain data for easy querying can utilize a Subgraph Manifest.
When Is Subgraph Manifest Used?
A Subgraph Manifest is used during the development and deployment phases of creating a subgraph.
It is essential when setting up the initial configuration for data indexing.
Whenever there are updates or modifications in the smart contracts or data requirements, the manifest is updated accordingly.
Where Is Subgraph Manifest Utilized?
Subgraph Manifests are utilized within The Graph protocol ecosystem.
They are typically stored in the project’s repository and are referenced by The Graph’s node services.
This enables decentralized indexing and querying of blockchain data.
Why Is Subgraph Manifest Important?
Subgraph Manifests are crucial because they define how data is indexed and queried from the blockchain.
They allow for efficient and scalable data extraction, making it easier to develop decentralized applications.
By using Subgraph Manifests, developers can ensure that their applications can interact seamlessly with blockchain data.
How Is Subgraph Manifest Created And Used?
Creating a Subgraph Manifest involves defining it in a YAML file format.
The process starts by specifying the data sources, such as smart contracts, and the events to be indexed.
Next, entities and their fields are defined for querying purposes.
Once the manifest is complete, it is deployed to The Graph’s decentralized network.
The Graph nodes then use this manifest to index the specified data and make it available for querying.
This entire workflow ensures efficient and decentralized access to blockchain data.
