I’m constantly getting this log in my var/debug.log file. I’m quite curious about this. I do not understand what it means.

main.DEBUG: cache_invalidate: {“method”:”GET”,”url”:”http://127.0.0.1/m4/paym/redirect/?SID=rpgvdrc7v23j38i36i8a274ae1″,”invalidateInfo”:{“tags”:[“vendor_payment_gateway_2″,”FPC”],”mode”:”matchingTag”},”is_exception”:false} []

I some how figured out that it has some connetions with my resource model collection which is as below:

class Collection extends \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection {      protected $  _idFieldName = 'id';      protected $  _eventPrefix = 'vendor_payment_gateway';      protected $  _eventObject = 'createorder_collection';      /**      * Define resource model      *      * @return void      */     protected function _construct()     {         $  this->_init('Vendor\Gateway\Model\Createorder', 'Vendor\Gateway\Model\ResourceModel\Createorder');     }  } 

Being a magento developer I must understand what my logs are saying. Can anybody help with this?
