List Backend

The List backend collects records and maintains a log of activity. As records are passed to the List backend, it adds each record to a row of the list. The records are added chronologically to the list.

Data is sorted and maintained by type. When you configure a List backend, you define a set of columns for a particular list. Each row of the list has a value specified for each column. To help you visualize a List backend, think of it as table in a database.

One of the columns in the List is always labeled "time", which is the time that the Engine recorded a piece of data. Each record is timestamped to the nearest second.
