Mongo Connector is a generic connection system that integrates MongoDB with another system using simple CRUD operational semantics, allowing users to connect MongoDB to search engines, secondary clusters, relational databases, integration platforms, and other storage systems. The connector supports both Sharded Clusters and standalone Replica Sets, abstracting MongoDB internals, and provides a lightweight DocManager API for implementing CRUD operations. Mongo Connector is designed to be easy to use, with implementations available for Solr, ElasticSearch, and MongoDB, and can be installed using pip. It allows users to sync their data between MongoDB and other systems, such as search servers or relational databases.
