引擎层 Coordinator HetuEngine计算实例的管理节点，提供SQL接收、SQL解析、生成执行计划、执行计划优化、分派任务和资源调度等能力。 Worker HetuEngine计算实例的工作节点，提供数据源数据并行拉取，分布式SQL计算等能力。
如需修改动态生效时间，请参考3.e修改“coordinator.config.properties”和“worker.config.properties”中的参数“catalog.scanner-interval”值为需要设定的动态生效时间，例如： catalog.scanner-interval
COLUMNS TERMINATED BY 用于指定列分隔符。该参数仅在CSV格式下需设置，且仅能指定单字节分隔符。 FORMAT AS 用于指定文件类型，支持CSV、JSON、PARQUET和ORC格式，默认为CSV。
