<p class="text-justify">This library has been specifically designed for production systems that must process massive data.
The library includes adaptors for Apache Hive, Apache Pig, and PostgreSQL (C++). These adaptors also stand as examples for adaptors for other systems.
The sketches in this library are designed to have compatible binary representations across languages (Java, C++, Python) and platforms.

<p class="text-justify">Built-in Theta Sketch set operators (Union, Intersection, Difference)
produce sketches as a result (and not just a number) enabling full set expressions of cardinality,
such as ((A ∪ B) ∩ (C ∪ D)) \ (E ∪ F).
This capability along with predictable and superior accuracy
(compared with <i>Include/Exclude</i> approaches) enable unprecedented analysis capabilities
for fast queries. </p>
