Although Azure Data Factory facilitates the ETL pipeline process using GUI tools, developers have less flexibility as they cannot modify backend code. On the other hand, Data bricks implement a programmatic approach that provides the flexibility of fine-tuning codes to optimize performance. The biggest...

最后,Airflow 不提供内置的数据存储解决方案。用户需要配置外部数据库(例如 PostgreSQL、MySQL)进行元数据和状态管理,这可能是额外的运营开销。 Azure Data Factory: What is it? Azure 数据工厂:它是什么? Azure Data Factory(ADF)is a cloud-based data integration service provided by Microsoft as part of its...
To move data to/from a data store that the service does not support, or to transform/process data in a way that isn't supported by the service, you can create aCustom activitywith your own data movement or transformation logic and use the activity in a pipeline. The custom activity runs...
Moving Data to Azure Data Lake Store The first step in the Web log analysis scenario is to move the data to ADL Store. You can move data to ADL Store using the Copy activity in an ADF pipeline. In order to do the copy operation, you need to create ADF linked services, datasets and...
A pipeline run in Azure Data Factory defines an instance of a pipeline execution. For example, let's say you have a pipeline that runs at 8:00 AM, 9:00 AM, and 10:00 AM. In this case, there are three separate pipeline runs. Each pipeline run has a unique pipeline run ID. A run...
