为什么不赞成将flink SplitStream标记为已弃用？ 将来会删除流吗？ 或者还有什么可以替代的

好像没有记录，但是，我发现不推荐使用此类的Pull Request。 https://github.com/apache/flink/commit/e0efabe8884f22b4a1c7ab9df3274b3fca03dcfb#diff-163a9f7f1b682eab706eb5e2a94faabcR36
通过查看此PR，您会发现它缺少以下描述：class User < ApplicationRecord
# has_secure_password
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:confirmable, :omniauthable, password_length: 8..36
has_many :identities
has_one :testimonials
has_many :questions
has_many :answers
def facebook
identities.where(provider: 'facebook').first
end
def facebook_client
@facebook_client ||= Facebook.client(access_token: facebook.accesstoken)
end
def twitter
identities.where(provider: 'twitter').first
end
def twitter_client
@twitter_client ||= Twitter.client(access_token: twitter.accesstoken)
end
def google_oauth2
identities.where(provider: 'google_oauth2').first
end
def google_oauth2_client
unless @google_oauth2_client
@google_oauth2_client = Google::APIClient.new(application_name: '',
application_version: '')
@google_oauth2_client.authorization.update_token!(access_token: google_oauth2.accesstoken,
refresh_token: google_oauth2.refreshtoken)
end
@google_oauth2_client
end
#validation for users

# validates_format_of :username, with: /^[a-zA-Z0-9_\.]*$/, :multiline => true

PASSWORD_FORMAT = /\A

end
看起来他们忘记添加原因和替代内容。

Side outputs比拆分/选择更灵活，更高效。
