Jeff Reback presented on the future of Pandas. He discussed the current state of Pandas, including its strengths (role in the Python data ecosystem), weaknesses (data types, APIs, performance), and challenges (in-memory format, lack of parallelism). He outlined a potential new architecture called Pandas2 that would use Apache Arrow for efficient data storage and Ibis for logical query planning to address Pandas' current limitations for large datasets. Pandas2 would allow parallel execution of computation graphs on distributed systems.
