What it is

Apache Druid is a high-performance, columnar, real-time analytics database designed for sub-second OLAP queries over massive datasets. It ingests streaming and batch data, stores it in compressed columnar format, and enables fast aggregations and searches across billions of rows. Druid powers dashboards, exploratory analytics, and operational monitoring at scale. Druid is organized as a Maven monorepo with module-based structure: cloud/aws-common and cloud/gcp-common contain cloud integration layers, codestyle/ enforces development standards (checkstyle, PMD, spotbugs configs), and the main source tree follows org/apache/druid/ package hierarchy. Core modules (processing, storage,…

Open these first:

  • README.md — Primary entry point documenting Apache Druid's purpose as a high-performance real-time analytics database and basic…
  • distribution/pom.xml — Root Maven POM defining the entire build system, dependencies, and module structure for the multi-module project.
  • cloud/aws-common/src/main/java/org/apache/druid/common/aws/AWSModule.java — Druid module pattern reference showing dependency injection and cloud provider integration architecture.
  • CONTRIBUTING.md — Governance and contribution workflow essential for understanding the project's maintenance model and review process.
  • codestyle/checkstyle.xml — Code quality enforcement configuration that all contributors must satisfy before merge.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/apache/druid.git && cd druid. Build: mvn clean install -DskipTests (inferred from Maven pom.xml structure). Verify: mvn verify to run tests and static checks. For development, i…

Daily commands:

Not directly inferrable from provided files; check README.md for quickstart. Druid typically runs as a cluster (coordinator, broker, historical, realtime) or embedded. Verify Maven profile and docker-compose presence…

Key cautions & unknowns

  • Concentrated ownership — top contributor handles 75% of recent commits
  • Maven parent POM required: all modules inherit from a parent at ../../pom.xml, so building individual modules requires the full repository context. DruidModule service loading: changes to AWS/GCP clients must…
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
