From the User Groups page of Talend Administration Center, you can organize existing users in groups based on their type (Data Integration/ESB, Data Management, Master Data Management, Data Preparation, Data Stewardship). Once created, these groups can be assigned to projects of the same type.
User groups allow administrators to manage large amount of users by organizing them efficiently in order to assign them easily to corresponding projects.
In case you have several licenses and one includes Big Data, you can narrow the scope of user groups to Big Data enabled users only.
To get a user's groups, use the getUserInfo command. For more
information about the MetaServlet parameters, see Parameters and actions in metaServlet.
