It also has a rich library of functions for array processing, datetime manipulations, machine learning, etc. Aggregation and Joins: KQL supports summarizing data through aggregation functions like summarize, count, avg, etc. You can also perform joins between tables, similar to SQL, with the join...
How to get started? For me the easiest was to get access toAzure's Data Explorerand start playing from there as it provides multiple datasets for interactiing and even allowing charts/dataviz rendering. You can also start fromMS Tutorialson how to write KQL queries. ...
