Description

In the WiredTiger engine many people know about its support for Btree (default) and the ability to enable LSM as well, but what few talk about is the In-Memory version of this engine. In this session, we will discuss what features do you get vs. lose when you move to in-memory. We will also discuss some use cases where it makes sense to use the in-memory options. This is meant to be a feature overview rather than an internals so it will help everyone understand more about this version of WiredTiger.
