• Types of Power BI Real-time Datasets

    January 31, 2017 / 2 Comments » / 7099 Views

    Everyone wants real-time BI, even when it doesn't have to be really "real time". Today Microsoft announced General Availability of Power BI Real-Time Streaming Datasets. There are actually three types of Power BI real-time datasets, as mentioned in the documentation. Push – Power BI permanently stores the data, enabling historic analysis, and reports creation atop the dataset. Behind the scenes, Power BI provisions an Azure SQL instance when the dataset is created. New data is pushed into SQL. Power BI then connects to that dataset via DirectQuery. Query Refresh (sending new queries to Azure SQL to update dashboard visuals) occurs whenever data is pushed in. When you create the dataset programmatically, you can specify a retention policy (defaultRetentionPolicy setting). When defaultRetentionPolicy is set to None, the dataset accumulates data to the maximum allowed Power BI limit (currently 1 GB). When set to basicFIFO, the dataset holds up to 200,000 rows and...

  • Unblocking the On-premises Data Gateway

    January 27, 2017 / No Comments » / 3945 Views

    Scenario: You have configured the Power BI on-premises data gateway for centralized data access and verified that its data sources test just fine. Direct query connections work. However, when you go to Power BI Service and attempt to schedule a data refresh for a dataset, you might find that the data gateway is disabled. Solution: The most common reasons for Power BI to disable the on-premises data gateway for refresh are: Unlike the personal gateway, the on-premises data gateway requires you to register data sources. You must go to the gateway properties and create data sources for all data sources used in your Power BI Desktop file. Unfortunately, as it stands Power BI doesn't allow you to select which data sources in the Power BI Desktop file will be refreshed and which ones don't require a refresh. It's all or nothing proposition. So, if one data source is not compatible...

  • Customer Success Case – ZynBit

    January 23, 2017 / No Comments » / 8930 Views

    One of our customers, ZynBit, made the Power BI blog today! Initially, ZynBit was considering Tableau but abandoned it in favor of Power BI because of the Power BI superior data modeling capabilities and the cost effective licensing model of Power BI Embedded. Prologika helped ZynBit to transition their solution to Power BI, including designing the data model and integrating reports with Power BI Embedded. Read our case study here.

  • Monitoring Progress of UPDATE

    January 22, 2017 / No Comments » / 4395 Views

    How to monitor the progress of an UPDATE statement sent to SQL Server? Unfortunately, SQL Server currently doesn't support an option to monitor the progress of DML operations. In the case of UPDATE against large tables, it might be much faster to recreate the table, e.g. with SELECT … INTO. But suppose that INSERT could take a very long time too and you prefer to update the data instead. Here is how to "monitor" the progress while the UPDATE statement is doing its job. Suppose you are updating the entire table and it has 138,145,625 rows (consider doing the update in batches to avoid running out of log space). Let's say the UPDATE statement changes the RowStartColumn column to the first day of the month: UPDATE bi.FactAccountSnapshot SET RowStartDate = DATEADD(MONTH, DATEDIFF(MONTH, 0, RowStartDate), 0); Use these statements to monitor the remaining work by using a reverse WHERE clause. Make sure to...

    January 19, 2017 / No Comments » / 30408 Views

    …with the second edition of my "Applied Microsoft Power BI" book. After seven books and starting from scratch every time, I finally got to write a revision! Thoroughly revised to reflect the current state of Power BI, it added more than 20% new content and probably that much content was rewritten to keep up with the ever changing world of Power BI. Because I had to draw a line somewhere, Applied Microsoft Power BI (2nd Edition) covers all features that were that were released by early January 2017 (including subscriptions). As with my previous books, I'm committed to help my readers with book-related questions and welcome all feedback on the book discussion forum on the book page. While you are there, feel free to check out the book resources (sample chapter, front matter, and more).

  • Power BI Subscriptions

    January 16, 2017 / No Comments » / 3884 Views

    Today Microsoft released a highly anticipated Power BI feature – subscribed report delivery. Similar to SSRS individual subscriptions, users can go to a Power BI report and subscribe to one or more of its pages to receive a snapshot of the page on a scheduled basis. The following scenarios are possible depending on the report data source: Imported datasets – the subscription follows the dataset refresh schedule. You'll get an email every time the scheduled refresh happens, so long as you haven't gotten an email in the last 24 hours. DirectQuery datasets – Power BI checks the data source every 15 minutes. You'll get an email as soon as the next check happens, provided that you haven't gotten an email in the last 24 hours (if Daily is selected), or in the last seven days (if Weekly is selected). Live connection to SSAS – Power BI checks the data source...
