    Methods

    • Deletes multiple keys and their associated values from the Cassandra database.

      Parameters

      • keys: string[]

        An array of keys to delete from the database.

      Returns Promise<void>

      A promise that resolves when all specified keys have been deleted.

    • Retrieves the values associated with an array of keys from the Cassandra database. It chunks requests for large numbers of keys to manage performance and Cassandra limitations.

      Parameters

      • keys: string[]

        An array of keys for which to retrieve values.

      Returns Promise<(undefined | Uint8Array<ArrayBufferLike>)[]>

      A promise that resolves with an array of Uint8Array or undefined, corresponding to each key.

    • Sets multiple key-value pairs in the Cassandra database. Each key-value pair is processed to ensure compatibility with Cassandra's storage requirements.

      Parameters

      • keyValuePairs: [string, Uint8Array<ArrayBufferLike>][]

        An array of key-value pairs to set in the database.

      Returns Promise<void>

      A promise that resolves when all key-value pairs have been set.

    • Yields keys from the Cassandra database optionally based on a prefix, based on the store's keyDelimiter. This method pages through results efficiently for large datasets.

      Parameters

      • Optionalprefix: string

        An optional prefix to filter the keys to be yielded.

      Returns AsyncGenerator<string>

      An async generator that yields keys from the database.
