The only real issue with Parquet, if you think a column based file format is the right fit for you (which it may not be) is that it was written to work on HDFS, and the specifics for block storage on HDFS. A lot of the benefits of Parquet are lost when you use it on other file systems.

A lot of the benefits are nicely present on my macbook. Compact size, fast querying with duckdb (columnar format + indexing), fast read/write for pandas, good type support… would recommend for local tabular data!
