Dynamics marketing analytics templates reports timeout

Hi Anonymous Thanks for the answer. In my path to the solution, I had applied your recommendations. I'm pretty sure that the problem is more the number of files than the size. I create a new blob storage and copied using ADF only one month of data (~ 600 MB and + 200k files). The size is under 1GB and the report failed refreshing from this new blob too. I ended up copying to a SQL Database the blobs and form that the report refreshed. I think the problem is searching into a blob with this number of files. I understand that search in a blob is more inefficient than in a DB because the data is unstructured and without order criteria but I wonder how is supposed to work the report templates with this architecture using blobs. Maybe I'm missing something. I was hoping this had happened to a lot of people working with these templates.
