Are you ready to dive into the world of real-time data analytics? EventQL, a distributed, columnar database, is here to empower you with its robust capabilities for handling large-scale data collection and analytics workloads. In this guide, we’ll walk you through the steps to get started with EventQL, its impressive features, and troubleshooting tips!

What is EventQL?

EventQL is a high-performance database designed to manage a massive volume of streaming writes while executing super-fast SQL and MapReduce queries. Think of it as a supercharged library that quickly organizes and retrieves thousands of books from different genres; each section is neatly categorized and ready for instant access!

Key Features of EventQL

• Automatic Partitioning: Tables are automatically split into partitions using a primary key, removing the burden of configuring shards beforehand.
• Idempotent Writes: Supports primary-key based INSERT, UPSERT, and DELETE operations for precise data ingestion from streaming sources.
• Compact, Columnar Storage: This function drastically reduces IO footprint and boosts query execution speed.
• Standard SQL Support: Almost complete SQL 2009 support, including JOIN operations, executed in parallel across multiple machines.
• Scales to Petabytes: With enough machines, you can manage vast amounts of data effortlessly.
• Streaming, Low-Latency Operations: Excellent for real-time data with minimal query latency (~0.1ms).
• Timeseries and Relational Data: Supports a variety of data types, including arbitrary JSON objects.
• HTTP API: Query results can be used in any application efficiently.
• Fast Range Scans: Efficient range scans on parts of the keyspace due to ordered table partitions.
• Hardware Efficient: Built with modern C++ for peak performance on standard hardware.
• Highly Available: A shared-nothing architecture ensures fault tolerance.
• Self-Contained: Setup a new cluster quickly; only requires Zookeeper for coordination.

Use Cases for EventQL

Here are scenarios where EventQL truly shines:

• Storage and analysis of streaming event, timeseries, or relational data.
• High volume event and sensor data logging.
• Joining and correlating timeseries data with relational tables.
