Added progress bar for indexing	NEXT-15366	OliverSkroblin	o.skroblin@shopware.com	OliverSkroblin

Core

• Added Shopware\Core\Framework\DataAbstractionLayer\Indexing\EntityIndexer::getTotal(), to find out the number of records of an indexer to be processed
• Added Shopware\Core\Framework\DataAbstractionLayer\Indexing\EntityIndexer::getDecorated(), to fulfill the decoration pattern requirements

---

Upgrade Information

Update EntityIndexer implementation

Two new methods have been added to the abstract Shopware\Core\Framework\DataAbstractionLayer\Indexing\EntityIndexer.

• getTotal - Shall return the number of records to be processed by the indexer on a Full index.
• getDecorated - Shall return the decorated service (see decoration pattern adr).

These two methods are declared as abstract with the 6.5.0.0. Here is an example of how a possible implementation might look like:

    public function getTotal(): int
    {
        return $this
            ->iteratorFactory
            ->createIterator($this->repository->getDefinition(), $offset)
            ->fetchCount();
        
        // alternate    
        return $this->connection->fetchOne('SELECT COUNT(*) FROM product');
    }

    public function getDecorated(): EntityIndexer
    {
        // if you implement an own indexer
        throw new DecorationPatternException(self::class);
        
        // if you decorate a core indexer
        return $this->decorated;
    }
