in Metabse, the dashboard has dozens of problems, and the data source table has 2000w pieces of data. During the query, high concurrency causes the problem of slow data loading. It takes more than 2 minutes to load a view, so how to solve it?
Post "Diagnostic Info" from Admin > Troubleshooting, and which driver you're developing and having problems with.
If the problem only happens in the driver, then it's likely a problem with the driver.
What do you mean by "high concurrency"?
