## What it is
Gremlin is the functional, data-flow graph traversal language of Apache TinkerPop, used to express complex queries over property graphs. This original repository is no longer active; development has moved to the Apache TinkerPop project.

## Use cases
- query a property graph with traversal steps
- find friends-of-friends relationships in a social graph
- run graph analytics like PageRank and connected components
- write graph queries portable across graph databases
- learn the Gremlin query language

## When to choose
- you need a vendor-neutral graph traversal language for OLTP or OLAP graph systems
- you want to query property graphs across multiple graph database providers

## When to avoid
- you expect active development in this repository - it has moved to Apache TinkerPop
- you need a non-JVM runtime without using the official TinkerPop language variants
- you need simple relational queries better served by SQL

## Facets
- artifact type: library
- maturity: abandoned
- function: database, search-engine, interpreter, sdk
- domain: databases, graph-processing, developer-tools
- platform: jvm, cross-platform
- tags: graph-traversal, gremlin, graph-query-language, property-graph, olap, oltp
