> Hi [@XiangpengHao](https://github.com/XiangpengHao) and [@waynexia](https://github.com/waynexia) is there a way to make the a website like in [parquet-viewer](https://parquet-viewer.xiangpeng.systems/) without reading the whole file from s3 like you implemented into the memory or are you saving it into filesystem? because as far as I know its not possible to read and write to filesystem in wasm as of yet? Parquet viewer does not read the whole file; it only reads the metadata and data relevant to your query. Try this example: https://parquet-viewer.xiangpeng.systems/?url=https%3A%2F%2Fhuggingface.co%2Fdatasets%2FHuggingFaceFW%2Ffineweb%2Fresolve%2Fmain%2Fdata%2FCC-MAIN-2014-42%2F000_00005.parquet You almost instantly get the query results even if the parquet file is a few GBs large. -- This is an automated message from the Apache Git Service.
