## What it is
Livy is an open-source REST service for interacting with Apache Spark remotely, supporting interactive Scala, Python, and R sessions as well as batch job submissions. It runs Spark locally or on YARN and allows multiple users to share the same server with impersonation support.

## Use cases
- submit spark jobs over rest
- run interactive pyspark sessions from a notebook server
- share a spark cluster among multiple users
- submit batch spark jobs from a web app
- run spark code remotely without installing spark locally

## When to choose
- you need remote REST access to a Spark cluster
- you want multi-user interactive Spark sessions with impersonation
- you submit Spark jobs from applications or notebooks over HTTP

## When to avoid
- you need a actively maintained project - releases are infrequent and the project is largely dormant
- you run Spark on Kubernetes and can use spark-submit or native schedulers instead
- you only need local single-user Spark development

## Facets
- artifact type: service
- maturity: maintenance
- function: http-server, rpc, api-framework
- domain: big-data, apis, microservices
- platform: jvm, self-hosted
- tags: apache-spark, rest-api, yarn, spark-submission, scala, data-engineering, linux, macos, web-server
