This feature is implemented in @graphprotocol/client-auto-pagination and installed automatically with the graph-client CLI package.

Usage Example

# .graphclientrc.yml
sources:
  - name: uniswap
    handler:
      graphql:
        endpoint: https://api.thegraph.com/subgraphs/name/uniswap/uniswap-v2
    transforms:
      - autoPagination:
          validateSchema: true # Validates that the schema source actually contains the required input filters.
          limitOfRecords: 1000 # Default is 1000, you can change if you indexer has different configuration in GRAPH_GRAPHQL_MAX_FIRST var.
