Parquet?
« on: March 27, 2024, 11:18:19 am »
Anyone with experience using Parquet files with Free Pascal? Looking for guidance on which libraries may have been successful.

Since no-one has a better answer, I think the solution is "Use DuckDB."

Someone has already started down that path.

I know from closeby that there is an implementation for most of Apache Hadoop in Delphi, but I am not aware if parquet is implemented as one of the underlying NoSQL parts. What I know is closed source and implemented in Delphi, not FreePascal.
bitrate is always calculated like this:sample rate * bitdepth * number of channels.
