Here's our take.

Azure Data Explorer

Nice Pick

Developers should learn Azure Data Explorer when working with large-scale, real-time data analytics, especially for use cases like application monitoring, IoT device telemetry, and security log analysis

Pros

• It is ideal for scenarios requiring rapid ingestion and querying of streaming data, such as operational intelligence, where traditional databases may struggle with performance
• Related to: kusto-query-language, azure-monitor

Cons

• Specific tradeoffs depend on your use case

Apache Druid

Developers should learn Apache Druid when building applications that require real-time analytics on massive datasets, such as monitoring systems, clickstream analysis, or IoT data processing

Pros

• It is particularly useful for use cases involving time-based queries, high-cardinality dimensions, and sub-second query latencies, where traditional databases like PostgreSQL or Hadoop might struggle with performance
• Related to: apache-kafka, apache-hadoop

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Azure Data Explorer is a platform while Apache Druid is a database. We picked Azure Data Explorer based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Azure Data Explorer wins

Based on overall popularity. Azure Data Explorer is more widely used, but Apache Druid excels in its own space.
