Interface ISecondaryEntityCache<TFields, TLoadParams>

An interface that knows how to load many objects from a cache by load params and invalidate those same load params.

interface ISecondaryEntityCache<TFields, TLoadParams> {
    invalidateManyAsync(
        loadParamsArray: readonly Readonly<TLoadParams>[],
    ): Promise<void>;
    loadManyThroughAsync(
        loadParamsArray: readonly Readonly<TLoadParams>[],
        fetcher: (
            fetcherLoadParamsArray: readonly Readonly<TLoadParams>[],
        ) => Promise<ReadonlyMap<Readonly<TLoadParams>, null | Readonly<TFields>>>,
    ): Promise<ReadonlyMap<Readonly<TLoadParams>, null | Readonly<TFields>>>;
}

    Read-through cache function.

    Parameters

    • loadParamsArray: readonly Readonly<TLoadParams>[]

      array of loadParams to load from the cache

    • fetcher: (
          fetcherLoadParamsArray: readonly Readonly<TLoadParams>[],
      ) => Promise<ReadonlyMap<Readonly<TLoadParams>, null | Readonly<TFields>>>

      closure used to provide underlying data source objects for loadParams

    Returns Promise<ReadonlyMap<Readonly<TLoadParams>, null | Readonly<TFields>>>

    map from loadParams to the entity field object
