@@ -78,7 +78,7 @@ A store node acts as a gateway to block data that is stored in an object storage
 It continuously synchronizes which blocks exist in the bucket and translates requests for metric data into object storage requests. It implements various strategies to minimize the number of requests to the object storage such as filtering relevant blocks by their metadata (e.g. time range and labels) and caching frequent index lookups.
 
 The Prometheus 2.0 storage layout is optimized for minimal read amplification. For example, sample data for the same time series is sequentially aligned in a [chunk file](design.md/#chunk-file). Similarly, series for the same metric name is sequentially aligned as well.
-The store node is aware of the files' layout and translates data requests into a plan of a minimum amount of object storage request. Each request may fetch up to hundreds of thousands of [chunks](design.md/#Note) at once. This is essential to satisfy even big queries with a limited amount of requests to the object storage.

Each request may fetch up to hundreds of thousands of [chunks](design.md/#chunk) at once. This is essential to satisfy even big queries with a limited amount of requests to the object storage.
 
 Currently, only index data is cached. [Chunk](design.md/#chunk) data could be cached but is orders of magnitude larger in size. In the current state, fetching chunk data from the object storage already only accounts for a small fraction of end-to-end latency. Thus, there's currently no incentive to increase the store nodes resource requirements/limit its scalability by adding chunk caching.
