title: How to manage airflow pools slots?
body: <p>I have the default pool with 128 slots.</p>
  <p>Now I have defined some other pools for each <code>business_unit</code>. A business_unit is a department, so the important data (prio 1) has the default pool available, but the prio 2 data has a pool for each <code>business_unit</code>.</p>
  <p>As I have 4 business_unit I have 5 pools:</p>
  <pre><code>1. default         --&gt; 128 slots
  2. business_unit_A --&gt; 8 slots
  2. business_unit_B --&gt; 8 slots
  2. business_unit_C --&gt; 8 slots
  2. business_unit_D --&gt; 8 slots
  </code></pre>
  <p>Here I have a doubt regarding how to manage the default one. As I created <code>4 new pools</code> with <code>8 slots</code> each one, I am using a total of <code>32 slots</code> of default. Should I redefine default pool as <code>96 slots</code>?</p>
  <p>Is the total number of slots available <code>128</code> and I have to play with it as the <code>100%</code> of
  &quot;available resources&quot;? Or can I add new pools with slots and airflow manages it behind it.
  Which one is the recommended?</p>
  <p>A task uses by default just 1 slot? If I increase it because it’s a large task the execution time should be faster? (does it relates with host resources)</p>
