Retain order of AND, OR filter children. (#10758) * Retain order of AND, OR filter children. If we retain the order, it enables short-circuiting. People can put a more selective filter earlier in the list and lower the chance that later filters will need to be evaluated. Short-circuiting was working before #9608, which switched to unordered sets to solve a different problem. This patch tries to solve that problem a different way. This patch moves filter simplification logic from "optimize" to "toFilter", because that allows the code to be shared with Filters.and and Filters.or. The simplification has become more complicated and so it's useful to share it. This patch also removes code from CalciteCnfHelper that is no longer necessary because Filters.and and Filters.or are now doing the work. * Fixes for inspections. * Fix tests. * Back to a Set.

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.
You can get started with Druid with our local or Docker quickstart.
Druid provides a rich set of APIs (via HTTP and JDBC) for loading, managing, and querying your data. You can also interact with Druid via the built-in console (shown below).
Load streaming and batch data using a point-and-click wizard to guide you through ingestion setup. Monitor one off tasks and ingestion supervisors.
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.
Use the built-in query workbench to prototype DruidSQL and native queries or connect one of the many tools that help you make the most out of Druid.
You can find the documentation for the latest Druid release on the project website.
If you would like to contribute documentation, please do so under /docs

Community support is available on the druid-user mailing list, which is hosted at Google Groups.
Development discussions occur on dev@druid.apache.org, which you can subscribe to by emailing dev-subscribe@druid.apache.org.
