What is the maximum data that can be imported to maria db from a .sql file

Hi Folks,

I am trying to import around 15mb of data (via a .sql file) in maria db through the import functionality; but it's not allowing and showing error message as shown below. Anyone knows what the alternative for this is as we are gonna import gb of data from the legacy system to appian as part of data migration. 

What is the max size that Appian maria db allows?

Regards,
