Specifying dataReductionAlgorithm in capabilities.json did the trick. Thanks a bunch. I can now read in 30K rows. My dataViewMappings now looks like this:
"dataViewMappings": [
{
"table": {
"rows": {
"select": [
{ "for": { "in": "values" } }
],
"dataReductionAlgorithm": { "sample": { "count": 64000 } }
},
"rowCount": { "preferred": { "min": 2, "max": 100000 }, "supported": { "min": 1, "max": 100000 } }
}
}
],
This is good progress. However, almost half of my table still gets truncated. Didn't the Power BI team say they were raising the 30K rows limit?
