## What it is
Mantis is a Netflix open-source stream processing platform written in Java for building realtime, cost-effective, operations-focused applications. It provides a distributed dataflow framework with connectors, serialization support, and deployment tooling for processing live event streams.

## Use cases
- process realtime event streams for operational monitoring
- build low-latency streaming data pipelines on the JVM
- analyze live metrics and logs from microservices
- develop cost-effective realtime alerting applications
- run distributed stream processing jobs in containers

## When to choose
- you need a JVM-based realtime stream processing platform focused on operations
- you want Netflix-proven streaming infrastructure with connectors and self-hosted deployment
- your workloads emphasize low-latency event processing over batch analytics

## When to avoid
- you need simple batch or ETL processing without streaming semantics
- you prefer managed cloud streaming services over self-hosted clusters
- your team is not comfortable with Java and distributed systems operations

## Facets
- artifact type: framework
- maturity: active
- function: streaming, message-queue, data-science, monitoring
- domain: big-data, microservices
- platform: jvm, self-hosted
- tags: realtime-stream-processing, reactive-streams, operations-analytics, netflix-oss, apache-license, data-engineering, real-time, devops, docker
