Docs - HLL lgK tip and slight layout change (#11482) * HLL lgK and a tip Knowledge transfer from https://the-asf.slack.com/archives/CJ8D1JTB8/p1600699967024200. Attempted to make a connection between the SQL HLL function and the HLL underneath without getting too complicated. Also added a note about using K over 16 being pretty much pointless. * Corrected spelling * Create datasketches-hll.md Put roll-up back to rollup * Update docs/development/extensions-core/datasketches-hll.md Co-authored-by: Abhishek Agarwal <firstname.lastname@example.org> Co-authored-by: Abhishek Agarwal <email@example.com>
Druid is a high performance real-time analytics database. Druid's main value add is to reduce time to insight and action.
Druid is designed for workflows where fast queries and ingest really matter. Druid excels at powering UIs, running operational (ad-hoc) queries, or handling high concurrency. Consider Druid as an open source alternative to data warehouses for a variety of use cases. The design documentation explains the key concepts.
Manage your cluster with ease. Get a view of your datasources, segments, ingestion tasks, and services from one convenient location. All powered by SQL systems tables, allowing you to see the underlying query for each view.
