1、商品上架

上架的商品才可以在网站展示。
上架的商品需要可以被检索。

1.1、设计：宽表设计

优点：方便检索
缺点：数据冗余

商品数据模型设计：

PUT product
{"mappings": {"properties": {"skuId": {"type": "long"},"spuId": {"type": "keyword"},"skuTitle": {"type": "text","analyzer": "ik_smart"},"skuPrice": {"type": "keyword"},"skuImg": {"type": "keyword","index": false,"doc_values": false},"saleCount": {"type": "long"},"hasStock": {"type": "boolean"},"hotScore": {"type": "long"},"brandId": {"type": "long"},"catalogId": {"type": "long"},"brandName": {"type": "keyword","index": false,"doc_values": false},"brandImg": {"type": "keyword","index": false,"doc_values": false},"catalogName": {"type": "keyword","index": false,"doc_values": false},"attrs": {"type": "nested","properties": {"attrId": {"type": "long"},"attrName": {"type": "keyword","index": false,"doc_values": false},"attrValue": {"type": "keyword"}}}}}
}

index:false 不允许检索
doc_valuses：false 不允许聚合

库存字段设计：true or false
无需存储具体库存。便于维护。只用在库存没有或者有了的情况下维护两次

###先不执行这个。后面上架时再执行这个
