A list of core operators is available in the documentation for apache-airflow: Core Operators and Hooks Reference. Subclasses should implement this, running whatever logic is Here is a list of operators and hooks that are released independently of the Airflow core. Use_task_execution_day ( bool) – deprecated parameter, same effect as use_task_logical_dateĪbstract method to choose which branch to run. Apache Airflow Python DAG files can be used to automate workflows or data pipelines in Cloudera Data Engineering (CDE). Execution Date is Useful for backfilling. Use_task_logical_date ( bool) – If True, uses task’s logical date to compare Of days can also be provided using a set. You get all the features and benefits of Amazon EMR without the need for experts to plan and manage clusters. Week_day ( str | Iterable | | Iterable ) –ĭay of the week to check (full name). Amazon EMR Serverless is a serverless option in Amazon EMR that makes it easy for data analysts and engineers to run open-source big data analytics frameworks without configuring, managing, and scaling clusters or servers. # import WeekDay Enum from import WeekDay from import EmptyOperator workday = EmptyOperator ( task_id = "workday" ) weekend = EmptyOperator ( task_id = "weekend" ) weekend_check = BranchDayOfWeekOperator ( task_id = "weekend_check", week_day =, use_task_logical_date = True, follow_task_ids_if_true = "weekend", follow_task_ids_if_false = "workday", ) # add downstream dependencies as you would do with any branch operator weekend_check > Parametersįollow_task_ids_if_true ( str | Iterable ) – task id or task ids to follow if criteria metįollow_task_ids_if_false ( str | Iterable ) – task id or task ids to follow if criteria does not met operator but I am getting a modulenotfound error in the Airflow logs. Some popular operators from core include.

Mime_subtype ( str) – MIME sub content type HiveOperator This operator executes hql code or hive script in a specific Hive database. Html_content ( str) – content of the email, html markupįiles ( list | None) – file names to attach in email (templated)Ĭc ( list | str | None) – list of recipients to be added in CC fieldīcc ( list | str | None) – list of recipients to be added in BCC field Subject ( str) – subject line for the email. To ( list | str) – list of emails to send the email to. Often it is confusing to decide when to use what. EmailOperator ( *, to, subject, html_content, files = None, cc = None, bcc = None, mime_subtype = 'mixed', mime_charset = 'utf-8', conn_id = None, custom_headers = None, ** kwargs ) ¶īases: Airflow provides a variety of operators to couple your business logic into executable tasks in a workflow. What is not part of the Public Interface of Apache Airflow?Ĭlass . The Airbyte operator allows you to trigger Airbyte OSS synchronization jobs from Apache Airflow, and this article will walk through configuring your Airflow DAG.

The Operator defaults to http protocol and you can change the schema used by the. For historical reasons, configuring HTTPS connectivity via HTTP operator is, well, difficult and counter-intuitive.

Configuring https via SimpleHttpOperator is counter-intuitive. Using the Public Interface for DAG Authors Use the SimpleHttpOperator to call HTTP requests and get the response text back.
