Android MySQLi send large number of requests to the server

I check that user Likes Given that or not, by this link:

for any GET request to the server from user:

#

 // my request link in android app, with volley library
 www.mydomain.com/check_user_like.php?user_id=userId&post_id=postID

 // check_user_like.php
 $user_id = $_GET['user'];
 $post_id = $_GET['post_id'];

 // check if exists row (mysqli)
 select id
 from likes_tbl
 where
      likes_tbl.user_id = $user_id
      and
      likes_tbl.post_id = $post_id
 limit 1

 if($num_row > 0)
      return true;
 else
      return false;



 // result in my android app
 if (result == true)
      textView.setText("post is liked");
 else
      textView.setText("post is not liked");

I have 100,000 user and 50,000 post in database. If, for example, I get 1,000 or 10,000 # Requests per second to the server, Is this a problem with the number of requests to the server?
