Hi, I used the copy command for upserting data for >1k rows as you mentioned but sometimes my lambda fails because the temp parquet file is not getting deleted in the temp path and next run says error as "temp path is not empty". Can you help?

Hi, yes I have experienced this issue before. Make your temp directory unique to avoid this problem. You can use the python UUID library to generate a unique id for each sub directory.
