parallel

The parallel tag allows you to designate a chunk of content to be rendered using a new thread. This tag is only available if you provide an ExecutorService to the main PebbleEngine.

{{ upperContent }}

{% parallel %}
    {{ calculation.slowCalculation }}
{% endparallel %}

{{ lowerContent }}

In the above example, the slow calculation will not block the lowerContent from being evaluated concurrently.
