RxJs: Incrementally push stream of data to BehaviorSubject<[]> : <p>Basically I'm trying to inflate <code>BehaviorSubject&lt;[]&gt;</code> with array of data which will be loaded in chunks.</p>

<p><code>BehaviorSubject&lt;[]&gt;</code> will be added with new chunk of data (like <code>Array.push</code>) but I don't want to use another array to store and add to <code>BehaviorSubject.next</code> because this will cause rendering to take too long as the data grow over time.</p>

<p>Any suggestion?</p>
