What are expensive queries in The Graph indexer node?
I'm curious about the concept of expensive queries in The Graph indexer node software. I've come across methods that read a file of expensive queries, but I'm unsure of what exactly qualifies as an expensive query in the context of Graph. Could someone please provide a clear definition or explanation of what constitutes an expensive query in The Graph ecosystem?

1An expensive query refers to a query that is more complex or resource-intensive. While an indexer would be able to provide a more detailed explanation, I can offer some insights. There are a few reasons why a query might be considered expensive:
-
Subgraph optimization: If a subgraph is not properly optimized or contains a large number of entities, it can result in a higher cost to query. Subgraphs that are well-optimized can provide faster and more efficient queries, reducing the associated costs.
-
Complex queries: Another factor that can contribute to an expensive query is the complexity of the query itself. For example, searching for information on all NFTs can involve a significant amount of data retrieval, resulting in higher costs.
It's important to note that the cost of a query is typically measured in terms of Graph Tokens (GRT), the native token of The Graph protocol. The more resources required to execute a query, the more GRT it will cost.
In summary, an expensive query is one that is more complicated or resource-intensive, either due to subgraph optimization issues or the complexity of the query itself. Optimized subgraphs and well-designed queries can help reduce the costs associated with querying The Graph protocol.

The Graph is a decentralized protocol for indexing and querying blockchain data. The Graph makes it possible to query data that is difficult to query directly.
