Why my exports are limited to 100 records only in django-import-export?

Question

I am using Django import export in my project.

I have ~5000 records in the model.

In local, The export is working fine. [exporting all the records in csv] But in production, when I export to csv, Only 100 records are exported.

The django app is hosted on Cpanel. I am using mysql phpmyadmin in production.

Is there any limit in the cpanel to export in django import-export module which I can change because the problem I am facing in production only.

database config in settings.py

DATABASES = {
    'default': {
        'ENGINE': 'mysql.connector.django',
        'NAME': '********',
        'USER': '*********',
        'PASSWORD': '*********',
        'HOST': 'localhost',
        'PORT': '3306',
        'OPTIONS': {
            'sql_mode': 'STRICT_ALL_TABLES',
        },
    }
}
