CMS.QUERY returns the estimated count of each item in the Count-min sketch at key. An estimate is never below the item’s true count, and can be above it. Items never counted usually report 0.

Return value

Section titled “Return value”

An array with one integer per item, the same in RESP2 and RESP3.

Error replies: CMS: key does not exist, and WRONGTYPE if the key holds another type.
