ValidationCache

This extension adds LRU caching to the validation step of query execution to improve performance by caching the validation errors in memory.

Usage example:

import strawberry
from strawberry.extensions import ValidationCache
 
schema = strawberry.Schema(
    Query,
    extensions=[
        ValidationCache(),
    ]
)

API reference:

class ValidationCache(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:

import strawberry
from strawberry.extensions import ValidationCache
 
schema = strawberry.Schema(
    Query,
    extensions=[
        ValidationCache(maxsize=100),
    ]
)
