EventQL is a distributed, columnar SQL database written in C++ for large-scale data collection and analytics, supporting streaming writes, automatic partitioning, and massively parallel SQL and MapReduce queries. It exposes an HTTP API and native TCP protocol and scales across shared-nothing clusters to petabyte-scale tables.

Use cases

• run fast analytical SQL queries over petabytes of data
• ingest high-volume streaming event data with exactly-once upserts
• store and query timeseries data across a cluster
• query distributed tables with automatic partitioning and parallel execution
• perform fast range scans over ordered key ranges
• insert arbitrary JSON objects into rows via a HTTP API

When to choose

• you need a self-hosted, horizontally scalable columnar analytics database with streaming writes
• you want MPP-style parallel SQL queries on commodity hardware
• your workload mixes timeseries, relational, and JSON data with a good primary key

When to avoid

• you need actively maintained software with recent releases and security patches
• you need full SQL feature coverage or rich ecosystem/tooling support
• you prefer managed cloud databases or row-oriented OLTP workloads
