Session
The Python data ecosystem is migrating from NumPy-based arrays toward Apache Arrow. Polars is built entirely on Arrow, and Pandas is heading in the same direction. Yet differences in string encoding, missing values, schemas, and index metadata make interoperability between the two formats surprisingly costly and error-prone. This talk examines these challenges through a case study of how ArcticDB, the open-source client-side dataframe database, navigated this same migration.
