## What it is
Drasi is a Data Change Processing platform that monitors data sources for changes, evaluates them against continuously running Cypher queries, and triggers reactions automatically. It ships as an in-process Rust library (drasi-lib), a standalone server, and a Kubernetes-based platform.

## Use cases
- detect when a database row changes and trigger an alert
- monitor sensor data and react when a threshold is crossed
- build change-driven notifications without polling
- detect absence of expected data changes
- join and cross-reference changes across multiple data sources
- stream CDC events from PostgreSQL into custom reactions

## When to choose
- you need real-time reactions to data changes without polling or copying data to a data lake
- you want declarative Cypher queries instead of stitching together CDC, message queues, and stream processors
- you run Kubernetes and need scalable change detection across many sources

## When to avoid
- you only need simple batch ETL or scheduled data pipelines
- your sources lack change feeds or logs Drasi can monitor
- you need a fully managed SaaS event-processing service

## Facets
- artifact type: framework
- maturity: active
- function: streaming, database, message-queue, workflow-automation
- domain: databases, microservices
- platform: cross-platform, rust, cli
- tags: change-data-capture, cdc, continuous-queries, cypher, event-processing, reactive, real-time, data-engineering, automation, kubernetes, docker
