Mongodb 3.0 supports user-defined storage engines, which can be configured to use mmapv1 or wiredTiger storage engines.

And the data file format generated by the 2 storage engines is not compatible. This means that the data file generated by the mmapv1 engine cannot be read by the wiredTiger engine.
1: If you want to know which engine MongoDB is enabled, the easiest way to view data files. The data file in the following format appears when the wiredTiger storage engine is started:

mongoVE connection effect:

3: Start the mmapv1 storage engine mongod --storageEngine mmapv1 --dbpath data directory:

mongo connection is as follows:


mongoVE connection is shown in the following image:


That's all: If there are any mistakes, please correct them.
