  • the “what” is interesting on interfaces or when you generate documentation with some tool like sphinx or javadoc.

    the “why” is interesting when you are somewhere inside a class or function and do something in a “strange” way, to work around a quirk in the codebase or something like that, or when you employ optimizations that make the code harder to read or atleast less obvious why somethings are done.








  • parquet is cloesely tied to the apache foundation, because it was designed as a storage format for hadoop.

    But many data processing libraries offer interfaces to handle parquet files so you can use it outside of the hadoop eco system.

    It’s really good for archiving data, because the format can store a lot of data with relatively low disk space, while still providing ok read performance because often times you won’t need to read the whole file due to how they are structured, where csv files would be a lot of plaintext taking up more diskspace.
