Upgrade Notes

When upgrading to this version, we recommend taking a brief look into these changes:

• Gas metering #2414
  • Now there's a gas limit for subgraph mappings, if the limit is reached the subgraph will fail with a non-deterministic error, you can make them recover via the environment variable GRAPH_MAX_GAS_PER_HANDLER
• Improve our CacheWeight estimates #2935
  • This is relevant because a couple of releases back we've added a limit for the memory size of a query result. That limit is based of the CacheWeight.

These are some of the features that will probably be helpful for indexers 😊

• Allow placing new deployments onto one of several shards #3049
• GraphQL route for dumping entity changes in subgraph and block #3275
• Unused deployments are automatically removed now #3023
  • The interval can be set via GRAPH_REMOVE_UNUSED_INTERVAL
• Setup databases in parallel #3019
• Block ingestor now fetches receipts in parallel #3030
  • GRAPH_ETHEREUM_FETCH_TXN_RECEIPTS_IN_BATCHES can be set to true for the old fetching behavior
• More robust proofOfIndexing GraphQL route #3348
  • A token can be set via GRAPH_POI_ACCESS_TOKEN to limit access to the POI route
• The new graphman commands 🙂
