None of the other sketches in this library have been designed for concurrent operation and should be considered <strong>not thread safe</strong>.</p>

The goal of this paper is to do an objective comparison of the <em>HllSketch</em> versus the Google <em>ZetaSketch</em> implementation, which is based on Google’s HyperLogLog++ paper[4]. These tests were performed on the <em>HllSketch</em> Apache DataSketches-java release version 1.2.0-incubating and on the HLL++ <em>ZetaSketch</em> version 0.1.0.</p>

+<p>The IntegerSketch has two update methods, one for <em>String</em> keys and an <em>Integer</em> value and the other for <em>long</em> keys and an <em>Integer</em> value.
 The user system code would call one of these two methods to update the sketch.  In our example, we will call the second update method with an integer value representing a user ID and a value of one for the Integer.  The key will be hashed and passed to the internal sketching algorithm that will determine if the key-value pair should be retained by the sketch or not.  If it is retained, the 2nd parameter will be passed to the IntegerSummary class for handling.</p>
