mongo-op-throttler
Applies a list of mongo operations at a limited speed.
Usage
mongo-op-throttler takes a oplog and runs the operations in the oplog against a Mongo at a fixed rate. It applies the operations in an idempotent way which means that inserts are converted to upserts, and the like. We do this so that even if we fail half-way through applying oplog operations we don't have to know where we failed and can simply re-run the job with the same input.
It has only been tested against the Mongo 2.4 version of oplogs, but in theory should work with other versions.
go run main.go --mongoURL localhost --path oplog.bson
You can specify the following flags
| flag | default | description |

--speed |
1 |

--mongoURL |
localhost |
Mongo URL to run the operations against |
--path |
/dev/stdin |
Oplog file to replay |
