Thanks if you can provide any insight. I have been performing a full refresh on a model.
```
{
"refresh": {
"type": "full",
"objects": [
{
"database": "Model1"
}
]
}
}
```
I would like to take a more granular approach and perform dataOnly refreshes on certain tables and then perform a calculate on the model.
```
{
"refresh": {
"type": "dataOnly",
"objects": [
{
"database": "Model1",
"table": "Table1"
},
{
"database": "Model1",
"table": "Table2"
}
]
}
}

{
"refresh": {
"type": "calculate",
"objects": [
{
"database": "Model1"
}
]
}
}
```
My question is, are these two methods equivalent? Is the full doing anything that the dataOnly/calculate does not.
Thanks

This author in the comments seems to indicate that the two methods are equivalent.

https://chris.koester.io/index.php/2017/06/21/process-ssas-tabular-tables-partitions-tmsl/

This documentation suggest starting with a Clearvalues.

https://learn.microsoft.com/en-us/analysis-services/tmsl/sequence-command-tmsl?view=asallproducts-allversions

So my current method is to Refresh-Clearvalues and then Refresh-DataOnly on each dimension. Then do the same for facts in a subsequent process. Then do a Calculate on the entire model.

I may try to do further analysis using profiler and if I find anything interesting I will post back.

I posted the results of my experiences testing different refresh scenarios. You can view that post here:
