因为默认cube.js dremio 查询1s 延迟的问题，进行了调整（参考了bigquery driver 的模式）

- 代码说明
具体可以参考github
使用说明
因为cube.js 目前处理数据driver 方言的问题，需要自己配置下，参考
// Cube.js configuration options: https://cube.dev/docs/config
const {DremioDriver,DremioQuery} = require("@dalongrong/mydremio-driver")
module.exports = {
dialectFactory: (dataSource) => {
// need config datasource for multitenant env
return DremioQuery
},
queryTransformer: (query, { securityContext }) => {
console.log(securityContext)
return query;
},
dbType: ({ dataSource } = {}) => {
return "mydremio"
},
driverFactory: ({ dataSource } = {}) => {
return new DremioDriver({})
}
};
说明
关于cube.js 集成dremio驱动的修改已经pr了，但是官方暂时还没有合并，如果需要提高查询速度的可以基于此进行扩展，npm包已经发布了
可以直接使用@dalongrong/mydremio-driver
