TYPO3: Disable cache of custom DataProcessor output - typo3

Question

I have an own DataProcessor, fetching and returing a random record.
This works as long as cache is disabled. How can I disable caching of this specific dataprocessor to display another result on every page load?
Like COA_INT would do?
My DataProcessor:
public function process(
ContentObjectRenderer $cObj,
array $contentObjectConfiguration,
array $processorConfiguration,
array $processedData): array
{
$heroResult = $this->heroQueryBuilder->fetchRandom($cObj->data['uid']);
$heros = $this->dataMapper->map(Hero::class, $heroResult);
if (count($heros)) {
$hero = $heros[0];
if ($hero instanceof Hero) {
$targetVariableName = $cObj->stdWrapValue('as', $processorConfiguration, 'hero');
$processedData[$targetVariableName] = $hero;
}
}
return $processedData;
}
My query builder statement, returning one result sorted random:
public function fetchRandom(int $pageUid, int $limit = 1): array
{
return $this->queryBuilder
->select('*')
->where(
$this->queryBuilder->expr()->eq('pid', $this->queryBuilder->createNamedParameter($pageUid, \PDO::PARAM_INT))
)
->addSelectLiteral('rand() AS random_sort')
->orderBy('random_sort')
->from(self::TABLE_NAME)
->setMaxResults($limit)
->execute()
->fetchAll();
}
Calling the dataProcessor in my page object:
page = PAGE
page {
10 = FLUIDTEMPLATE
10 {
dataProcessing {
20 = TYPO3\CMS\Frontend\DataProcessing\MenuProcessor
20 {
special = list
special.value = 1
as = rootpage
dataProcessing {
10 = Vendor\Extension\DataProcessing\HeroProcessor
10 {
as = hero
}
}
}
}
}
}
Rendering the result in my page layout
<f:if condition="{rootpage.0.hero}">
<div class="c-page__hero">
<f:render partial="Page/Hero/Hero" arguments="{hero:rootpage.0.hero}" />
</div>
</f:if>
How can I disable caching just for this specific DataProcessor? Do I have to convert the cObj e.g. by calling $cObj->convertToUserIntObject()? Any ideas?

Answer 1

Solved by creating a COA_INT object. Thought, there might be a better way without having to use f:cObject viewhelper.
lib.hero = COA_INT
lib.hero {
10 = FLUIDTEMPLATE
10 {
file = {$pmWebsite.view.partialRootPath}/Page/Hero/Hero.html
dataProcessing {
10 = Vendor\Extension\DataProcessing\HeroProcessor
10 {
pid = 1
as = hero
}
}
}
}
