Hi,

depending on your mongodb version you should use inMemoryExperiment or ephemeralForTest in the storage engine config for the community edition

The enterprise version comes with something way better from what I hear

Thanks for your answer! I could not find inMemoryExperiment storage engine. I am using master version - 3.3.9. which version includes it?
Thanks again.

Welcome

For that version I guess it is ephemeralForTest. I run 3.2 and that is what I am using.

For the 3.3 branch rocksdb should also be a valid option

You are using a version that is not quite stable for a feature that has Test in the title or has just arrived

Good luck

Hi revit,

The MongoDB Enterprise build contains the in-memory storage engine for production use, and starting from MongoDB Enterprise v3.2.6 is part of general availability in the 64-bit builds. This storage engine uses document-level concurrency control for write operations. As a result, multiple clients can modify different documents of a collection at the same time. To enable, please use --storageEngine inMemory option.

If you are looking for a non-persistent storage engine for testing purposes, the ephemeralForTest storage engine is available in the community build starting from MongoDB v3.2. This storage engine supports a collection-level locking. You can enable this storage engine by specifying --storageEngine ephemeralForTest. As the name suggests, it is for testing purposes and not suitable for production use.

I appreciate any help in downloading the source code.

You can review the source code files on MongoDB git project for ephemeralForTest

I am using master version - 3.3.9.

Note that an odd numbered major releases like 3.3.x are only intended for development/testing purposes. For more information on the version numbering scheme, see MongoDB Version Numbers.
