4.2.1
Fixed
OrderItemCountAggregator/OrderItemAmountAggregator: replaced the per-order N+1 collection loading (fullsales_orderscan plus one order-item collection load per order, every cron minute) with a single streamed query oversales_order_item. Item status is derived from the qty columns mirroringMagento\Sales\Model\Order\Item::getStatusId(), including children-inherited backorder; emitted series and labels are unchanged. The aggregators no longer unserializeproduct_options, so a corrupt row cannot abort the whole metric anymore. (#66)
Note: supersedes the 4.2.0 tag, which is not installable via composer (its composer.json version field still said 4.1.0).
