ParserCache

This extension adds LRU caching to the parsing step of query execution to improve performance by caching the parsed result in memory.

Usage example:

import strawberry
from strawberry.extensions import ParserCache

schema = strawberry.Schema(
    Query,
    extensions=[
        ParserCache(),
    ],
)

API reference:

class ParserCache(maxsize=None):
    ...

maxsize: Optional[int] = None

Set the maxsize of the cache. If maxsize is set to None then the cache will grow without bound.

More examples:

Using maxsize

import strawberry
from strawberry.extensions import ParserCache

schema = strawberry.Schema(
    Query,
    extensions=[
        ParserCache(maxsize=100),
    ],
)
