When we create a fresh union object we need to know lgk. Incoming compact theta sketches don't have any notion of lgk in them. This can be different for other sketches (like HLL or CPC), but we decided to always pass lgk to union (implicitly or explicitly). Regarding accuracy. The user can get slightly more accurate results by setting higher lgk to union even with lower lgk sketches. In a general case I would suggest to start from the desired accuracy and set lgk accordingly for every step, but in some cases the user might not have control over previous steps. -- This is an automated message from the Apache Git Service.
