Magento2 : What is the default table used by Bestsellers in the admin?

Question

In the database, I know that there are 3 aggregated bestseller tables

sales_bestsellers_aggregated_daily,
sales_bestsellers_aggregated_monthly,
sales_bestsellers_aggregated_yearly

but which one of them is the default?

Answer 1

Dashboard bestseller usese Report/Bestseller resource model that can be found in:

vendor\magento\module-sales\Model\ResourceModel\Report\Bestsellers.php

And as you can see in constructor that it uses AGGREGATION_DAILY by default

$this->_init('sales_bestsellers_aggregated_' . self::AGGREGATION_DAILY, 'id');

From the look of this, I can say it uses sales_bestsellers_aggregated_daily table for this report

Answer 2

The bestsellers table on the dashboard is an "all time" display of data.
