MongoDB oplog replay utility.
OplogReplay provides a simple tool that can replay MongoDB oplogs from one cluster to another. Useful for admin operations, or to keep multiple copies of the same data in different mongo clusters.
The included bin/oplogreplay script should cover most of the usecases:
oplogreplay source:27017 destination:27017 --logpath=oplogreplay.log
(see oplogreplay –help for more details)
Installing is as easy as:
pip install oplogreplay
- The package contains only two classes:
More advanced use-cases can be achieved by extending the OplogReplayer (e.g.: you can choose to skip replaying deletes, or modify the operations before replaying them into the destination cluster, etc.).
