Comparing duckdb and duckplyr to tibbles, data.tables, and data.frames (CC279)

Описание: duckdb has quickly grown in popularity as a database platform that is super fast with large datasets. Watch as Pat shows how to generate a duckdb database and access values from the database. He'll also compare the performance of using duckdb directly and using duckplyr or using tibbles, data.tables, and data.frames. Pat will discuss how the perforance changes by the number of different key values and the size of the database. You'll likely be surprised by the results! This episode is part of an ongoing effort to develop an R package that implements the naive Bayesian classifier.
