apache/druid: README-based editorial guide

apache/druid describes itself in the README as "Apache Druid: a high performance real-time analytics database.". This article keeps to facts that can be checked in the repository. Stars, forks, and promotional badges are signals of attention, not proof of quality. Under "README", the README says: | Workflow | Status | | :----------------------------------- | :----------------------------------------------------------- | | ⚙️ CodeQL Config | [ |. That establishes the project's stated boundary, not a production test.

The README's "Community" section gives a useful starting point for deciding whether the project fits: Druid development discussions take place in the druid-dev. For live conversations, join the #dev channel on Slack.. If that problem is not yours, popularity is a poor reason to adopt it. Project names, commands, and component names are kept as written so a reader can return to the primary source without guessing at terminology. Another checkable README item is: Druid users can find help in the druid-user mailing list on Google Groups, and have more technical conversations in #troubleshooting on Slack.. It can shape a first test, but it does not replace testing in the intended environment.

The operating model is spread across sections such as "Apache Druid". The source evidence includes: 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.. This article does not turn missing architecture, performance, or security details into claims. A real deployment still needs a look at the repository layout, configuration files, and release history.

Start installation from the README's documented entry point. A command that can be checked in the source is: README 没有给出可直接复制的安装命令。 When the README contains no runnable command, this article does not invent one. Open its "Getting started" section and confirm system dependencies, default ports, and first-run initialization before using a public server.
