Therefore, miHoYo requires a logging platform with high stability, elastic scalability, and high performance to meet their growing requirements on data analysis and their need to perform intensive operations for Genshin Impact.


The Genshin Impact team faced the following challenges after the release of Genshin Impact:

  • Data growth

    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.

  • Centralized data collection

    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.

  • Traffic spikes

    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 Genshin Impact team requires a logging platform that provides the auto scaling feature to implement rapid scaling during peak hours.
