# alibaba/MongoShake

MongoShake is a universal data replication platform based on MongoDB's oplog. Redundant replication and active-active replication are two most important functions. 基于mongodb oplog的集群复制工具，可以满足迁移和同步的需求，进一步实现灾备和多活功能。

## What it is
MongoShake is a Go-based universal data replication platform built on MongoDB's oplog, fetching changes from a source MongoDB and replaying them into a target database or forwarding them through pluggable tunnels such as RPC, file, TCP, or Kafka. It supports redundant and active-active replication with parallel replication and checkpoint-based high availability.

## Use cases
- migrate data between MongoDB clusters
- set up active-active MongoDB replication
- build a disaster-recovery replica of a MongoDB database
- stream MongoDB oplog changes to Kafka
- sync a sharded MongoDB cluster to another cluster
- subscribe to MongoDB change events in real time

## When to choose
- you need continuous MongoDB-to-MongoDB replication or migration with minimal downtime
- you want to fan out oplog changes to Kafka or custom consumers
- you need parallel, checkpointed replication with high availability

## When to avoid
- your source database is not MongoDB
- you need a simple one-time backup rather than live replication
- you require a fully managed cloud sync service without operating your own tooling

## Facets
- artifact type: service
- maturity: active
- function: database, message-queue, streaming, etl, backup
- domain: databases, microservices, self-hosted
- platform: go, self-hosted
