However, following the launch of the platform, a member of the Player team built a job to aggregate our player data (which we call pings) in realtime into a Datadog dashboard that the team could use to monitor the impact of player releases. We then develop tools so that this data is easily accessible, scalable, and flexible for internal and external customers. There are 3 operators, each representing a SQL query. TiDB is compatible with the MySQL 5.7 protocol. The team can spot spikes in error rates or player setup times across various dimensions such as region, browsers or operating systems. KDA provides the underlying infrastructure for your Flink applications. Low learning and configuration costs. Additionally, we have containerized the whole platform so users can develop locally. As a result, we are always collecting more data and offering aggregations across more dimensions. Previously Rong held a software and machine learning engineer position in Qualcomm computer vision team. For example, in IT Operations Analytics, it is paramount that Ops get critical alert information in real-timeor within acceptable latency (near real-time) to help them mitigate downtime or any errors caused due to misconfiguration.
