## What it is
ToroDB Stampede replicates data from a MongoDB replica set into relational tables in PostgreSQL, translating the document structure into normalized tuples. It enables running SQL analytics and complex aggregate queries on MongoDB data with better performance.

## Use cases
- run SQL analytics on MongoDB data
- migrate from MongoDB to SQL
- replicate MongoDB collections into PostgreSQL tables
- speed up aggregate queries on document data
- give BI tools access to MongoDB data via SQL

## When to choose
- you need relational/BI queries over MongoDB data and can run a replication service
- you want a normalized SQL schema rather than a JSONB dump
- PostgreSQL is your analytics backend

## When to avoid
- you need an actively maintained project (last release 2018)
- you only need to store JSON documents in Postgres without normalization
- you don't control a MongoDB replica set

## Facets
- artifact type: application
- maturity: abandoned
- function: database, etl, streaming
- domain: databases, analytics
- platform: jvm
- tags: mongodb, postgresql, nosql-to-sql, replication, data-migration, data-engineering, linux, docker
