业务痛点 Challenges

《原神》上线后面临的挑战主要表现为以下方面：
The
Genshin Impact
team faced the following challenges after the release of
Genshin Impact
:
数据增长
"Data growth"
《原神》上线后，在短短一个月内，月活跃用户规模已经达到千万级别。随着用户数量的快速增长，以及游戏运营体系的逐步精细化，客户业务数据量也在快速的增长。如何实现大规模数据场景下的高性能查询分析成为《原神》团队迫切需要解决的问题。
Only one month after the release of
Genshin Impact
, the number of active players per month exceeded 10 million. The data volume increased at a high speed with the rapid growth of players and the optimization of the operations system. Therefore, the
Genshin Impact
team required a solution to query and analyze large volumes of data with high performance.
集中采集
"Centralized data collection"
除在中国市场广受欢迎外，《原神》在海外市场同样火爆，荣登美国、德国、加拿大、韩国、新加坡等国家
APP Store
畅销榜榜首。然而全球化也带来了数据日志集中采集困难，可靠性低的问题。
Genshin Impact
became popular worldwide and topped the App Store bestseller list in the United States, Germany, Canada, Republic of Korea, and Singapore. However, the globalization of the game also increased the difficulty of centralized data collection and required higher stability.
突增流量
"Traffic spikes"
作为一款开放世界冒险游戏，《原神》结合游戏地图内每个地区不同的时节、文化背景创作了丰富的活动内容，同时假期活动及版本更新也将带来流量的突增。因此《原神》便需要有一款高弹性的日志平台来帮助产品实现流量突发期的快速扩容。
Genshin Impact
is an open-world adventure game that offers promotional activities based on different seasons and cultural backgrounds of each region in the game map. Holiday activities and version updates result in traffic spikes. Therefore, the
