I have two questions regarding ODBC connections
I use odbc to run queries in Oracle DB, and I would like to know if there is some performance issue with connecting to diferent databases inside the same dashboard, or if we should use only one database / schema per dashboard.
Q2: i have a query that I run in SQL Developer, and uses an index (timestamp field). The same query ran through power bi creates a explain plan in which the index is not used. Any ideas?
Thank you for any help

Hi @nranito,
Q1. Per my knowledge, if you would load a large number of data from multiple data bases, you'd better create multple .pbix files and each report connects to a single dataset. Because loading too much data into desktop might slow down the query execution, and might cause out of memory error.
Q2. You should convert the timestamp field to date/time type. Power Query; Convert Time Stamp to Date Time
Best regards,
