A baseline update (also called a full update) produces a complete re-indexing of the entire data set. It runs the update process for the whole data set.
In your baseline update pipeline, you can add, change or remove records, dimensions, dimension values and properties. In addition, configuration changes, such as dimension reordering or stop word changes require a baseline update.
You can run baseline updates nightly and use this method as your update strategy. For small to medium-sized data sets, baselines can be run frequently, as often as every few minutes. Alternatively, you can run as many partial updates as needed for those changes that can be done through partial updates, and periodically run baseline updates for those changes that require a baseline update.
