What are the different refresh options at Data Source(s) to overcome Power BI Refresh Limitation

To overcome Power BI refresh limitations at the data source level, you can employ various strategies to ensure that data is updated and available for analysis. Here are different refresh options at the data source(s) level:

  1. Change Data Capture (CDC):
    • Implement Change Data Capture mechanisms at the source database to capture and track changes to the data.
    • Use CDC to identify new or modified data since the last refresh and only refresh the incremental changes in Power BI.
  2. Scheduled Extract, Transform, Load (ETL) Jobs:
    • Schedule periodic ETL jobs to extract data from source systems, transform it as needed, and load it into Power BI.
    • Use ETL tools such as Azure Data Factory, SSIS, or custom scripts to automate data extraction and loading processes.
  3. Data Replication:
    • Replicate data from source systems to a staging or data warehouse environment using replication tools or techniques.
    • Refresh data in Power BI from the staging or data warehouse environment, which can have more predictable and controlled refresh processes.
  4. Streaming Data:
    • Stream data directly from source systems using real-time data streaming technologies such as Kafka, Azure Event Hubs, or AWS Kinesis.
    • Power BI can connect to streaming data sources to provide real-time insights without relying on batch refreshes.
  5. DirectQuery Mode:
    • Configure Power BI datasets to use DirectQuery mode, where queries are sent directly to the underlying data source in real-time.
    • DirectQuery mode ensures that users always access the latest data without the need for scheduled refreshes.
  6. API Integration:
    • Integrate Power BI with source systems using APIs to retrieve data on-demand or at scheduled intervals.
    • Implement custom connectors or use existing connectors provided by Power BI to connect to APIs and fetch data.
  7. Web Scraping and Web Data Connector:
    • Use web scraping techniques or Power BI's Web Data Connector to extract data from web sources and refresh it periodically.
    • Web scraping can be useful for accessing data from websites or online databases that do not provide APIs.
  8. Manual Data Import:
    • Manually import data into Power BI using CSV or Excel files when automated refresh options are not feasible.
    • Although less efficient, manual data import can be useful for occasional or one-time data refreshes.

By leveraging these refresh options at the data source(s) level, you can ensure that data in Power BI remains up-to-date and relevant for analysis, thereby overcoming refresh limitations imposed by Power BI licensing or resource constraints.
