With the massive influx of IoT devices, the enterprise accumulated vast amounts of time-series data. Traditional databases proved ineffective at processing this data, resulting in high storage costs and inefficient data analysis. We developed a high-performance time-series database featuring high-throughput writing, efficient compressed storage, and rapid query analysis. Deploying this database reduced the company's data storage costs by 50% and increased data analysis efficiency by 4 times, providing robust support for equipment monitoring, fault early warning, and business decision-making.
