I am supposed to carry out compression on a cube. Everyday the loading to the target occurs and later indexing happens. The compression has to be done for requests since an year from today i.e. october 2013 till today. Should I wait until the loading and indexing happens or can I directly do the compression right away, and also I am supposed to do compression for 20 requests at a time and each request contains around 300,000 records. How can I do that?
