Gas errors on the network

A number of subgraphs on the network have hit the default gas limit, so indexers must configure a larger one. We should look into these with the purpose of adjusting gas costs that may be overestimated. These subgraphs have been reported as going over the limit:

The Eden Network (QmWd8mE5nedM5smvzQhDYmsWEcgiAtdqccdZ2XCsvCdVEK, source link case has more details. It fails with:

Probably due to iterating over a large collection, the network.stakers array might be as large as 4.5k entries.

Comienza con el fallo del límite de gas en el registro reportado y compáralo con el código fuente de Eden Network en packages/subgraph/src/network.ts, líneas 116-124, especialmente con la gran colección network.stakers. Traza cómo se mide esta ejecución en graph-node e identifica si el coste de gas informado está sobreestimado; se considera terminado cuando los subgraphs afectados ya no alcanzan el límite predeterminado sin requerir un aumento de configuración.
