sql server 2012 - How to process SSAS objects in SSIS (single task or multiple sub tasks)? -

-

i'm working on ssis , ssas build bi plateform.

i develop ssis worflow process ssas objects. so, want use 'analysis services processing task` job.

enter image description here

in case, there 8 cubes using more thant 15 dimensions (a dimension can used few cubes).

should process ssas objets using 1 analysis services processing task or can split them different sub tasks. example, 1 package each sub task including 'analysis services processing task'.

so example :

  • package 1 - task 1 - processing dimensions
  • package 2 - task 2 - processing cube 1
  • package 3 - task 3 - processing cube 2
  • ...

is approach more efficient if 1 asp task can use parallel process ?

thanks !

normally, go simplest way of running "process full" of complete database. analysis services takes care of dependencies, , uses multiple parallel threads process everything. , default, part of 1 single transaction, i. e. if fails, stays in original, consistent state, , users see original state during processing, , new state after processing completes successfully. there no intermediate, half-new , half-old state visible users.

only of there reasons deviate simple approach, use different approach. reasons be:

  • it takes long re-process everything, , know parts of source data changed , not.
  • you want avoid loose several hours of processing due problem occurs in late processing step, , can live inconsistency caused parts being processed, , not.
  • your server has limited resources, , default processing of analysis services ambitious , stops due trying parallelize much, , gets stuck there few resources. similarly, not have enough disk space on server host 2 copies of data necessary transaction processing.
  • ...

the first 1 one.
