The difference between MongoDB high version and low version

One. MongoDB Engine:

MONGODB 3.0 supports user-defined storage engines, which users can configure using the Mmapv1 or Wiredtiger storage engine.

The Wiredtiger storage engine, which was opened by default after version 3.2 , was previously used by the MMAPV1 storage engine. and the data file format generated by the 2 storage engines is incompatible. That is, the MMAPV1 engine generates a data file Wiredtiger engine that does not read it.

To start the MMAPV1 engine command:

Mongod--storageengine mmapv1--dbpath Data Catalog:

To start the Wiredtiger engine command:

Mongod--storageengine wiredtiger--dbpath Data Catalog:
