springboot和shardingjdbc实现分表，不需要分库，其中我的表结构包括id，设备编号，温度，适度，采集时间，然后查询的话，需要各种维度的查询，时间范围查询，根据设备编号查询，根据设备编号加时间范围查询，上面的分页和不分页，根据di查询等等多种查询方式Kimi:我来为你设计一个完整的 Spring Boot + ShardingJDBC 分表方案。针对你的物联网数据采集场景，我建议采用时间维度分片（按月分表），同时兼顾设备编号查询性能。分片策略设计考虑到你的查询需求： - 主分片键：采集时间（collect_time）- 按月分表 - 次维度：设备编号（device_no）- 建立索引表结构设计– 逻辑表：sensor_data– 物理表：sensor_data_202401, sensor_data_202402, …CREATE TABLEsensor_data_202401(idBIGINT NOT NULL AUTO_INCREMENT,device_noVARCHAR(64) NOT NULL COMMENT ‘设备编号’,temperatureDECIMAL(5,2) COMMENT ‘温度’,humidityDECIMAL(5,2) COMMENT ‘湿度’,collect_timeDATETIME NOT NULL COMMENT ‘采集时间’,PRIMARY KEY (id),INDEXidx_device_time(device_no,collect_time),INDEXidx_time(collect_time)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;2.
