<h1>Near-Sortedness in Indexes</h1>
<p>
Real-world data ingestion is rarely perfectly sorted — incoming records often arrive
<b><b><em>nearly</b></b></em>
sorted, with a small fraction entries displaced.
What happens when such workloads are <b><b><em>ingested</b></b></em>
into an index? <br>
This demo lets you configure near-sorted data using the K-L-sortedness
metric, visualize the data, and ingest such near-sorted streams into
indexes that adapt to sortedness, as well as classical B+trees. <br>
