Hi, I need to come and ask here, I did not find enough information so I hope I am just having a bad day or somebody is censoring my search results for fun... :)
I would like to import (lots of) Apache parquet files to a PostgreSQL 11 cluster - yes, I believe it should be done with the Python pyarrow module, but before digging into the possible traps I would like to ask here if there is some common, well understood and documented tool that may be helpful with that process?
It seems that the COPY command can import binary data, but I am not able to allocate enough resources to understand how to implement a parquet file import with that.
I really would like follow a person with much more knowledge than me about either PostgreSQL or Apache parquet format instead of inventing a bad wheel.
Any hints very welcome,
thank you very much for your attention!
John
