 - `max_item_size`: maximum size of an item to be stored in memcached. This option should be set to the same value of memcached `-I` flag (defaults to 1MB) in order to avoid wasting network round trips to store items larger than the max item size allowed in memcached. If set to `0`, the item size is unlimited.

 - `read_timeout`: the redis read timeout.
 - `write_timeout`: the redis write timeout.
 - `cache_size` size of the in-memory cache used for client-side caching. Client-side caching is enabled when this value is not zero. See [official documentation](https://redis.io/docs/manual/client-side-caching/) for more. It is highly recommended to enable this so that Thanos Store would not need to continuously retrieve data from Redis for repeated requests of the same key(-s).

 Here is an example of what effect client-side caching could have:
