  • Synchronizing two streams with Kusto

    We discussed Azure Data Explorer (ADX) and its query language Kusto in a past article.

    In this article I want to talk about a typical problem in real time analytics: synchronizing two streams of data.

    This happens all the time when sensor data are produced by different devices. Different devices may record measurements...
