DQ+ running an analysis : What are the fields that can be used to go over the memory?

You have the option to override the default execution settings that are used when the Analysis is executed by using one or more of the following properties:

• Execution Property - Select this option, then click the Add button, to create new execution properties.
• Execution Profile - Select a predefined execution profile to inherit the execution settings from a profile that has been created on your environment by an administrator.
• Overriding Execution Sizing - Select this option to edit the execution settings for the selected Analysis. The options that are available, and the default values, will vary according to the selected Cluster Type.

You may want to use a combination of the above settings. For example, an Execution Profile may include execution sizing configuration that you want to inherit on your Analysis, but you may want to also add a new execution property for this specific Analysis.
Or, you could choose to override the execution sizing settings of the Execution Profile while inheriting the execution properties defined on the profile.

Within your Analysis' Edit Stage window, you can click Settings in the top right (like below):
