Of course, the drawback of this, is that you can make changes using Tabular Editor, which causes the model to enter a state where it is only partly queryable or not queryable at all. Potentially, a refresh operation can take a long time to complete, during which no additional metadata may be updated on the server. This is by design, to ensure that saving metadata changes to Analysis Services does not take too long. Tabular Editor does not automatically trigger refresh operations in Analysis Services when changes are made to the data model. In summary, these connected features are: Using Tabular Editor 3 as an external tool for Power BI Desktop.
Loading a model directly from SQL Server Analysis Services, Azure Analysis Services or the Power BI XMLA endpoint.This can be beneficial to other community members reading this thread.The phrase "connected to an instance of Analysis Services" means any one of the following: Please remember to click "Mark as Answer" the responses that resolved your issue, and to click "Unmark as Answer" if not. a single large recalc – choose wisely based on your specific processing scenario.įor more information, please refer to below document: So your choice is multiple small recalcs every time vs.

However there is a tradeoff – if you perform multiple Process Full or Process Default operations in a row, the engine performs the recalculationĮvery time. Want to limit the scope of recalculation, you might want to do a Process Full or Process Default instead of Process Data. This means that after a Process Data operation on a dimension, you may be stuck recalculating a large fact table when it was not impacted by the initial processing operation. Keep in mind that you can only issue Process Recalc at the database level. Also, you don’t need to issue a Process Recalc after you merge partitions through the SSMS UI, as the UI automatically executes a Process Recalc for you All of those commands recalculate theĪffected objects (and only the affected objects) for you. The last thing you do, and you can batch up as many processing operations as you want before issuing that last Process Recalc.You do not need to Process Recalc if you do a Process Add, Process Full, or Process Default. Your model may be unqueryable if you skip the Process Recalc. Also, after you merge partitions in script, you must perform a Process Recalc. To answer this, you might need to dig more into "Process Recalc".Īny time after you do a Process Clear or Process Data, you must issue a Process Recalc. >Question - what magic did Case 2, it saved 27 minutes? why after detach and attach, it not actually processing hierarchy and relationship. Question - what magic did Case 2, it saved 27 minutes? why after detach and attach, it not actually processing hierarchy and relationship. I see the cube is accessible and able to build reports. I don't see any logs stating it is processing hierarchy or relationship.
Detach and Attach the cube (took 2-3 mins)ģ. Process Partition P101 - Process Data, takes 4-6 minsĢ.
I understand it does hierarchy and relationship processing for the whole table. I do see logs stating it is processing hierarchy or relationship.ġ. Process Partition P100 - Process Data, takes 4-6 minsĢ. However if done differently (case 2 below), it completed fast.ġ. ReCalc, which takes long time - 30 minutes. Incremental processing of partition - Process Data takes ~6 minutes, but after all partition processing, it is followed by process The model - the fact table is partitioned by day.
