Node.JS如何创建拼花地板文件并保存到Minio
以下面NPM文档()中的示例为例,如何将生成的拼花地板文件直接写入minio。我希望避免将拼花地板文件写入磁盘,然后执行第二次操作将文件移动到minio中 下面的示例在调用close()后立即将文件写入磁盘Node.JS如何创建拼花地板文件并保存到Minio,node.js,parquet,minio,Node.js,Parquet,Minio,以下面NPM文档()中的示例为例,如何将生成的拼花地板文件直接写入minio。我希望避免将拼花地板文件写入磁盘,然后执行第二次操作将文件移动到minio中 下面的示例在调用close()后立即将文件写入磁盘 // advanced fruits table let schema = new ParquetSchema({ name: { type: 'UTF8' }, colours: { type: 'UTF8', repeated: true }, stock: { re
