Corona Technical Series: Time-Series Databases in Corona
The article explains how Corona leverages three time‑series databases—InfluxDB for storing pre‑aggregated user metrics and platform health data, ClickHouse for real‑time multidimensional log analysis with aggregations, and ElasticSearch for full‑text searchable log monitoring—detailing their schema designs and query examples.
Corona 技术专题系列文章: 时序数据库在 Corona 中的应用
本文介绍三款数据库在 Corona 时序分析场景下的应用: InfluxDB、ClickHouse、ElasticSearch。
1. InfluxDB: 用于存储 C 端用户上报的预聚合结果数据和平台自身运行健康度的原始数据。
2. ClickHouse: 用于实时在线分析原始日志，提供多维组合筛选、平均值、分位数、PV、UV 走势等分析。
3. ElasticSearch: 用于存储异常监控的原始日志，提供全文检索和时序分析。
具体应用场景包括:
InfluxDB 用于存储 C 端预聚合结果和平台健康度数据。
ClickHouse 用于实时分析原始日志，支持多维组合筛选和实时聚合。
ElasticSearch 用于日志搜索和时序分析。
表结构设计和查询示例详见原文。
