Forbid easily misused HashSet and HashMap constructors (#9165)
* Forbid easily misused HashSet and HashMap constructors

* Add two LinkedHashMap constructors to forbidden-apis and create utility method as replacement for them

* Fix visibility of constant in CollectionUtils.java

* Make an exception for an instance of LinkedHashMap#<init>(int) because proper sizing is used

* revert changes to sql module tests that should be in separate PR

* Finish reverting changes to sql module tests that were flagged in checkstyle during CI

* Add netty dependency resulting from SupressForbidden

Apache Druid

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.

Getting started

You can get started with Druid with our 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 data

data loader Kafka

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 the cluster

management

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.

Issue queries

query view combo

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.

Documentation

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 in this repository and submit a pull request.

Community

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.

Chat with Druid committers and users in real-time on the #druid channel in the Apache Slack team. Please use this invitation link to join the ASF Slack, and once joined, go into the #druid channel.
