impala-ruby

build   rubygems

This is a ruby client for Cloudera Impala. You use it like this:

require 'impala'

Impala.connect('host', 21000) do |conn|
  conn.query('SELECT zip, income FROM zipcode_incomes LIMIT 5')
end
# => [{:zip=>'02446', :income=>89597}, ...]

You can also use cursors to avoid loading the entire result set into memory:

conn = Impala.connect('host', 21000)
cursor = conn.execute('SELECT zip, income FROM zipcode_incomes ORDER BY income DESC')

one_row = cursor.fetch_row
cursor.each do |row|
  # etc
end

conn.close
