> *Function definition:* 
> Clear the cache of chunk, chunk metadata, timeseries metadata and bloom filter to release the memory footprint.
> In cluster mode, we must consider the distinction between requests to clear the cache of a single node or the entire cluster.
> The syntax definition might look like this:
> CLEAR CACHE (ON (LOCAL | CLUSTER))?
