The mongo-connector-transaction project originated as a project that is based on already exists mongo-connector.
This repository and the library it provides are just for supporting mongo-connector to be able to work with transactions process as when it was built it doesn't consider the different oplog structure for the transaction oplog documents.
Currently it only supports integration with elastic2-doc-manager
For complete documentation, check out the Mongo Connector Wiki.
`Note`: Pardon me if the documents could be a little missy but the library supports everything that mongo-connector used to support but you shall add -transaction part only.
mongo-connector-transaction 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.
mongo-connector-transaction supports Python 3.4+ and MongoDB versions 3.4 and 3.6.
To install mongo-connector-transaction with the MongoDB doc manager suitable for replicating data to MongoDB, use pip:
pip install mongo-connector-transactionThe 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-transaction |
| Elasticsearch 5.x | pip install 'mongo-connector-transaction[elastic5]' |
You may have to run pip with sudo, depending on where you're installing mongo-connector and what privileges you have.
Mongo Connector provides support for installing and uninstalling itself as a service daemon under System V Init on Linux. Following install of the package, install or uninstall using the following command:
$ python -m mongo_connector.service.system-v [un]install
You can also install the development version of mongo-connector manually:
git clone https://github.com/AmrAdelKhalil/mongo-connector
pip install ./mongo-connectormongo-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 myDevReplSetTo initialize your server as a replica set, run the following command in the mongo shell:
rs.initiate()Once the replica set is running, you may start mongo-connector. The simplest invocation resembles the following:
mongo-connector-transaction -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-transaction --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:
Elasticsearch 2.x and 5.x: https://github.com/AmrAdelKhalil/elastic2-doc-manager
The MongoDB doc manager comes packaged with the mongo-connector project.
