Project description

Ownership of the mongo-connector repo has been transferred to YouGov. MongoDB would like to thank Jason Coombs, Executive Technical Director at YouGov, for agreeing to maintain this project.

For complete documentation, check out the Mongo Connector Wiki.

System Overview

mongo-connector creates a pipeline from a MongoDB cluster to one or more target systems, such as Solr, Elasticsearch, or another MongoDB cluster. It synchronizes data in MongoDB to the target then tails the MongoDB oplog, keeping up with operations in MongoDB in real-time. Detailed documentation is available on the wiki.

Getting Started

mongo-connector supports Python 2.6, 2.7, and 3.3+ and MongoDB versions 2.4, 2.6, 3.0, 3.2, and 3.4.


To install mongo-connector with the MongoDB doc manager suitable for replicating data to MongoDB, use pip:

pip install mongo-connector

The install command can be customized to include the Doc Managers and any extra dependencies for the target system.

Target System Install Command
MongoDB pip install mongo-connector
Elasticsearch 1.x pip install 'mongo-connector[elastic]'
Amazon Elasticsearch 1.x Service pip install 'mongo-connector[elastic-aws]'
Elasticsearch 2.x pip install 'mongo-connector[elastic2]'
Amazon Elasticsearch 2.x Service pip install 'mongo-connector[elastic2-aws]'
Elasticsearch 5.x pip install 'mongo-connector[elastic5]'
Solr pip install 'mongo-connector[solr]'

You may have to run pip with sudo, depending on where you’re installing mongo-connector and what privileges you have.


You can also install the development version of mongo-connector manually:

git clone
pip install ./mongo-connector

Using mongo-connector

mongo-connector replicates operations from the MongoDB oplog, so a replica set must be running before startup. For development purposes, you may find it convenient to run a one-node replica set (note that this is not recommended for production):

mongod --replSet myDevReplSet

To initialize your server as a replica set, run the following command in the mongo shell:


Once the replica set is running, you may start mongo-connector. The simplest invocation resembles the following:

mongo-connector -m <mongodb server hostname>:<replica set port> \
                -t <replication endpoint URL, e.g. http://localhost:8983/solr> \
                -d <name of doc manager, e.g., solr_doc_manager>

mongo-connector has many other options besides those demonstrated above. To get a full listing with descriptions, try mongo-connector --help. You can also use mongo-connector with a configuration file.

If you want to jump-start into using mongo-connector with a another particular system, check out:

The MongoDB doc manager comes packaged with the mongo-connector project.
