# KeyValueStorageManager\<T>

Defined in: [atomiq-storage-memory-indexed-kv/src/KeyValueStorageManager.ts:9](https://github.com/atomiqlabs/atomiq-storage-memory-indexed-kv/blob/e65067d59b4e9456247363a9f25e09e57be9f4c1/src/KeyValueStorageManager.ts#L9)

Simple `IStorageManager` adapter built on top of any `IKeyValueStorage` backend.

This is intended for chain-storage style data where values are accessed by id and no in-memory indexes are required.
