This experiment mainly used Alibaba Cloud's MongoShake open source tool. The experiment introduced the process of using the MongoShake tool to migrate self-built Mongodb replica set data to an Alibaba Cloud Mongodb instance. MongoShake is a general-purpose platform-based service tool written by Alibaba Cloud in Golang. It reads MongoDB's Oplog operation log to replicate MongoDB data to meet specific needs. MongoShake also provides log data subscription and consumption functions, which can be flexibly connected through SDK, Kafka, MetaQ, etc., and is suitable for scenarios such as log subscription, data center synchronization, and asynchronous Cache elimination.
