About supported amount of items at Trigger status in Zabbix3.4

[Yuasa]

<Question>
In case we will use setting with attached file"Admin-General-setting.jpg" and 1000 alarm are coming at 1 trigger from same IP within few sec,
the what list of trigger we can see at the GUI?

<Question of background>
Since we can limit how many items should be shown at the GUI wit "Limit for search and filter results=1000".
however i think the configuration can be limited only items of trigger(as blue square in attached file "question point.jpg") .

I'm thinking how to limit number of the same event(as red square in attached file "question point.jpg") .
because as worst case, if 1 event have huge event(like 1M event) , Zabbix might retrieve all data from DB with 1 query to show the list of trigger at the GUI.it might have huge impact to Zabbix resource. this is my concern points.

Here is what the doc says about: Limit for search and filter results

Maximum amount of elements (rows) that will be displayed in a web-interface list, like, for example, in Monitoring → Triggers or Configuration → Hosts.
Note: If set to, for example, '50', only the first 50 elements will be displayed in all affected frontend lists. If some list contains more than fifty elements, the indication of that will be the '+' sign in “Displaying 1 to 50 of 50+ found”. Also, if filtering is used and still there are more than 50 matches, only the first 50 will be displayed.
