Laravel Yajra Datatable Crashed While Loading Huge Data

I'm having trouble using Laravel Yajra Datatable to load 172.425 record with the following error:

> PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4096 bytes) in vendor/laravel/framework/src/Illuminate/Database/Connection.php on line 421.

I already tried to set my php ini memory limit from 128M to 512M then clear my cache and config using artisan command but nothing changes.

here's my code:

The Table

<div class="table-responsive">
        <table class="table table-striped" id="table_employee">
            <thead>
                <tr>
                    <th>No</th>
                    <th>Action</th>
                    <th>API</th>
                    <th>Description</th>
                    <th>Cors</th>
                    <th>Link</th>
                </tr>
            </thead>
            <thead>
                <tr>
                    <th></th>
                    <th></th>
                    <th class="th">API</th>
                    <th class="th">Description</th>
                    <th class="th">Cors</th>
                    <th class="th">Link</th>
                </tr>
            </thead>
            <tbody></tbody>
        </table>
    </div>

My JQuery for the Datatable

$(document).ready(function () {
    $('#table_employee').DataTable({
        processing  : true,
        serverSide  : true,
        responsive  : true,
        dom         : 'Bfrtip',
        initComplete: function() {
            this.api().columns().every(function() {
                var that = this;

                $('input', this.footer()).on('keyup change clear', function() {
                    if (that.search() !== this.value) {
                        that.search(this.value).draw();
                    }
                });
            });
        },
        ajax: "/api/getdata",
        columns: [
            {data  : 'DT_RowIndex', name  : 'DT_RowIndex'},
            {data  : 'action',      name  : 'action', orderable: false, searchable: false},
            {data  : 'API',         name  : 'API'        },
            {data  : 'Description', name  : 'Description'},
            {data  : 'Cors',        name  : 'Cors'       },
            {data  : 'Link',        name  : 'Link'       },
        ]
    });

    $('#table_employee thead .th').each(function() {
            var title = $(this).text();
            $(this).html('<input type="text" class="form-control rounded shadow" placeholder="search" />');
            
        });
});

and here's my controller:

function getdata(){

    $data = DB::table('royalti.testapi')->get();

    return DataTables::of($data)->addIndexColumn()
            ->addColumn('action', function($row){
                $btn = '<a href="javascript:void(0)" class="btn btn-info text-white btn-sm">' . $row->Cors . '</a>';
                return $btn;
            })
            ->rawColumns(['action'])
            ->make(true);
}

I run this program using my own personal laptop with 8GB of RAM. Any help would be appreciated.

You're doing get() so your controller fetching all the data first and then sending the data into yajra/datatable on frontend.

you can do it like this(enable paging:true in dt on frontend):

$model = ModelName::query();
$dt = new DataTables();
return $dt->eloquent($model)->toJson();

paging:true fetches only data to be displayed on datatable pagination.
Do it like this for using db facades:

$users = DB::table('tableName');
$dt = new DataTables();
return $dt->query($users)->toJson(); //datatables will do the rest

Loading all the records is not a smart thing to do

To improve the performance, it is better to use the paging feature

Also You can also reduce the amount of data by reducing the return columns
