Apache Druid is a column-oriented distributed database optimized for real-time OLAP (online analytical processing). It powers dashboards, alerts, and analytics at Netflix, Airbnb, Lyft. Salary: junior Druid engineers $80-110k USD; seniors $140-210k. Learning curve: 3-4 weeks to query, 3-6 months to design data pipelines. Adjacent to data warehouses, ClickHouse, and time-series databases.

Druid Analytics શું છે

Apache Druid is a distributed, column-oriented data store optimized for real-time OLAP (online analytical processing). It ingests streaming events (from Kafka, HTTP) and enables exploratory analytics: "show me pageviews by country for the last hour" in sub-second latency. Architecture: ingest events → store in columns → index → query in parallel across nodes → return results in milliseconds. Designed for dashboards, monitoring, and alert systems.

❓ FAQ

What's the difference between Druid and a traditional data warehouse?
Traditional warehouse (Snowflake, BigQuery): good for batch, ad-hoc queries, takes seconds. Druid: optimized for real-time, dashboards, sub-second latency. Druid = real-time OLAP; warehouse = analytical processing.
How does Druid achieve sub-second latency?
Column-oriented storage (only read columns you need), distributed indexing (parallel queries), and in-memory caching. Queries parallelized across nodes. Sub-second SLA requires proper schema design and indexing.
What data should I load into Druid?
Time-series metrics: pageviews, clicks, latency, server load, user events. Millions of events/day are ideal. Druid shines at: 'How many users in India in last hour?' or 'Top 10 countries by ad clicks in last day?'.
How do I ingest data into Druid?
Streaming (Kafka) for real-time: data flows from Kafka into Druid continuously. Batch (S3, local files) for historical: nightly imports. Hybrid: stream for today, batch import historical data.
What's the cost of running Druid?
Druid is open-source (free). Running costs: servers (memory-heavy), storage (less than warehouse due to compression). A 1PB/month event stream: 10-20 high-RAM nodes, ~$50-100k/month cloud cost.
