title: Firestore / Kotlin FieldValue arrayRemove() + Firestore pricing
body: <p>Firestore / Kotlin FieldValue arrayRemove() removes a known element on the array/list. My concern is to remove an element at a given position on the array, without konwing the element itself. Is it possible?</p>
  <p>For instance, if my list is {&quot;Mowgli&quot;, &quot;Baloo&quot;, &quot;Bagheera&quot;, &quot;Kaa&quot;, &quot;Shere Kahn&quot;}, I want to remove the fisrt element &quot;Mowgli&quot; without knowing the name &quot;Mowgli. Kind of:</p>
  <pre><code>FieldValue.arrayRemove([0])
  </code></pre>
  <p>Moreover, regarding pricing policy from google, is an 'arrayRemove' considered as a query, so that it is the same price than setting a full class of 10,000 elements?</p>
  <p>Thanks</p>
