Dash app does not update data from CSV file

Dash Python
1

I have created a Dash app that reads a CSV file to produce a DashTable. The table is updated every 15 minutes using a batch process independant of the Dash app. When I reload the Dash app it still displays the old table even though the csv file has been updated by the batch program. To up date the Dash table I need to kill the Dash server and start it up again. Why is this and how can I change the app so that it sees the updated csv file.

Thank you

I think is related with the way Dash works using the cache (not enough technical knowledge :woozy_face:).

Try using dcc.Interval to update the table every 15 minutes.
