I had to load data from a file that is not in:
C:\ProgramData\MySQL\MySQL Server 8.0\Uploads
Therefore, in my.ini file, I had to set --secure-file-priv=""
I was trying to run a python code (with connection to MySQL) that reads several .csv files (~1000 files with a total size of ~80GB) and save them in on table in an existing schema in MySQL. However, the data I was trying to load was to be save in a table that is not created in C:\ProgramData\MySQL\MySQL Server 8.0\Data, but in a folder in a different drive (not on C:).
While running the python code, an error (in Spyder for Python) was generated saying that the connection in MySQL was lost!!
I tried to figure out why this happened and how to fix it but i couldn't.
When I was trying to restart MySQL8.0 in "Services", I had an error message in the error file, as below (part of the message):

InnoDB: Progress in percents: 12020-02-20T15:44:08.160766Z 1 [Warning] [MY-010005] [Server] Skip re-populating collations and character sets tables in InnoDB read-only mode.
