The information needed to connect to external systems is stored in the Airflow metastore database. Airflow allows you to use your own Python modules in the DAG and in the Airflow configuration. Hooks implement a common interface when possible, and act as a building block for operators.Īirflow pools can be used to limit the execution parallelism on arbitrary sets of tasks. Hooks are interfaces to external platforms and databases like Hive, S3, MySQL, Postgres, HDFS, and Pig. Jinja is a modern and designer-friendly templating language for Python, modelled after Djangoâs templates. Now, Iâm still deliberating on if Iâm super cheap or the airflow metadata database doesnât really need to be THAT robust, so I opted for a free tier micro instance. Select the PostgreSQL logo, go for Version 9.6.X, whatever minor version is fine. The logical date and time for a DAG Run and its Task Instances. Go to databases section and Create database. Each task is an implementation of an Operator.Īn operator describes a single task in a workflow.Īn Operator that waits (polls) for a certain time, file, database row, S3 key, etc.Īn instance of a task - that has been assigned to a DAG and has a state associated with a specific DAG run (i.e for a specific execution_date). A Task defines a unit of work within a DAG it is represented as a node in the DAG graph, and it is written in Python.
