If you have used filters on status and/or on other columns which will always return less than 5000 items from list then it will not cause any problems.
Another way to avoid the issues due to threshold is add indexes on the columns you are using in filters(Check below link for more details).
So, either you should add filters to your REST query so that it will always return less than 5000 list items or you can use $top
as given below:
siteUrl/_api/web/lists/getbytitle('List Display Name')/items?$top=1000
Also, there are some ways to manage such large lists in SharePoint using indexes and folders which you can find in below article:
Manage large lists and libraries in SharePoint.
Also you can use recursive call to get 5000 items like given below:
var url = _spPageContextInfo.webAbsoluteUrl + "/_api/web/lists/getbytitle('ListName')/items?$select=Title&$top=1000&$skiptoken=Paged=TRUE";
var response = response || []; // this variable is used for storing list items
function GetListItems(){
return $.ajax({
url: url,
method: "GET",
headers: {
"Accept": "application/json; odata=verbose"
},
success: function(data){
response = response.concat(data.d.results);
if (data.d.__next) {
url = data.d.__next;
GetListItems();
} else {
return response;
}
},
error: function(error){
}
});
}
