Looks good; needs just a small touch-up for the docs
docs/environment-variables.md
Outdated
| - `GRAPH_STORE_DISABLE_CALL_CACHE`: Disables the store call cache entirely. Graph node will skip writing and reading from the | ||
| call cache. The buffered block call cache will still be enabled. This option may be useful | ||
| for indexers who are running their own RPC nodes. Disabling the store call cache may have | ||
| significant performance impact. (default: false) |

What do you mean by The buffered block call cache - do you mean just the block cache?
Also, I would reword 'Disabling the store call cache may have significant performance impact' to something like 'Disabling the store call cache may have significant performance impact; the precise impact depends on how long an eth_call takes on average compared to how long a database lookup of a cached call result takes'

I meant the in memory call cache that buffers the call results for a duration of a block, before the results is persisted in the DB. Will make this line more clear with something like Call results will still be cached in memory for the duration of a block

Aah; I wouldn't mention that here, it just complicates the description of the environment variable

Resolves #5513
What this PR does:
Introduces an environment variable
GRAPH_STORE_DISABLE_CALL_CACHEthat allows disabling the store call cache. The main motivation is to provide indexers, who use locally hosted RPC nodes, with an option to bypass the graph-node call cache.
