- Description about the talk
- I introduced Ruby and Apache Arrow integration including the "super fast large data interchange and processing" Apache Arrow feature at [RubyKaigi Takeout 2021](https://rubykaigi.org/2021-takeout/presentations/ktou.html).
This talk introduces how we can use the "super fast large data interchange and processing" Apache Arrow feature in Ruby. Here are some use cases:
* Fast data retrieval (fast `pluck`) from DB such as MySQL and PostgreSQL for batch processes in a Ruby on Rails application
* Fast data interchange with JavaScript for dynamic visualization in a Ruby on Rails application
* Fast OLAP with in-process DB such as DuckDB and Apache Arrow DataFusion in a Ruby on Rails application or irb session
