mysql2 streaming vs net_write_timeout
Demonstrates an issue where streaming silently abandons records behind.
Checkout the repo and adjust your mysql credentials in mysql2_streaming.rb.
The first command-line argument is used to set the session 'net_write_timeout'. This value could be set to a low value in your global mysql.conf, causing the issue to manifest unexpectedly in your code.
bundle install ruby mysql2_streaming.rb 10 # Works ruby mysql2_streaming.rb 1 # Fails
