Hi,
I have dataset with 15 million records and trying to merge with other dataset with approximately 100 records.
But, the merge process crashes out.
Just wanted to check if we have any limitations with merge.
Thanks,

Hi Yingjie,
Thanks for your response.
I am bit confussed, until now my visulization was using Direct Query mode and dataset was 15 millions records. And with each click it was taking approximately 50-60 seconds for page to refresh.
Reason for confussion is you were saying direct query has limitation 1 million, but I was able to work with 15 million but with delayed response time.
So now I changed to import mode and deleted all unrelated columns. But, now I see that .pbix file is too big approximately 8 MB.
Please guide me can I reduce the .pbix file size (with direct query mode file size was 150 KB)
Thanks,

Thanks Denis.
I have not applied any steps to my dataset, merge queries fails at initial source step.
And yes its a relational DB (MS SQL Server).
Thanks,

Hi @Anonymous ,
If you are using the direct query mode to connect to sql server, here is the limitation:
Limit of 1 million rows returned on any query:
There's a fixed limit of 1 million rows placed on the number of rows that can be returned in any single query to the underlying source. However, the limit can occur in cases where Power BI isn't fully optimizing the queries sent, and there's some intermediate result being requested that exceeds the limit.

Hi @Anonymous ,
what is your data source? Is it a relational database like SQL Server or CSV files?
Did you check if query folding happens until the end of the table? Then the merge could also happen on the database.
