Export versioned data using a changeset

If your chosen data has a primary key, you will be able to choose which updates you wish to export using a changeset.

For example, if there are 50 versions of a large data layer, and the user has downloaded version 39, the changeset will ensure that you get all the changes made in the intervening 11 versions.

A changeset outlines what has been added, updated or deleted in a particular data. A changeset can be used to update data, without having to download the entire dataset from scratch.
