None of what you're saying would give me concerns. Your machine seems powerful enough to handle the work and there doesn't seem to be any issues with what you're doing. How much data are you trying to process? How long does it take?
I have tables who can have more than 10 million record.
I first test the tool with a table (contains 50000 record's) sometimes it takes less than minut and sometimes it stop and i have this worning
That's why I think it's hardware (I need more free space may be)
Hmmm. I'd probably suggest opening a case with Tableau support on this one.
have you any idea please regarding my third question
3. I tried to create a join: between a customer table and a contact table but only choosing the minimum ( id contact) associate with each customer? is this join possible
And thank you for your help
I don't see why that wouldn't be possible. May require a couple of extra steps to first get the minimum ID, then join it back to the main table.
Ok thank you for your help
