 * `nodeWebkitAppName` (optional): if you are using NeDB from whithin a Node Webkit app, specify its name (the same one you use in the `package.json`) in this field and the `filename` will be relative to the directory Node Webkit uses to store the rest of the application's data (local storage etc.). It works on Linux, OS X and Windows.
 * `inMemoryOnly` (optional, defaults to false): as the name implies.
-* `pipeline` (optional, defaults to false): use pipelining. This is an experimental feature that speeds up writes (about 2x) but can sometime increase read times. You probably shouldn't use it yet.

 ### Speed

That said, it is still pretty fast on the expected datasets, especially if you use indexing.
