Indexer volume is the measurable flow of GraphQL queries your validator serves across assigned subgraphs each day. It differs from raw node uptime because volume captures actual useful work—queries answered correctly while respecting gas limits and client SLAs. Understanding volume prevents two mistakes: under-serving high-value contracts and over-committing on dead weight.
This guide structures indexer volume into four ordered phases—preparation, checks, execution, and review. Each phase contains observable completion criteria you can verify without guesswork. Follow them sequentially; skipping preparation causes downstream errors that inflate volume artificially and erode fee yield over time.
