Querying Kusto clusters with KQL
If, like me, you were not familiar with the idea of a Kusto cluster before learning about Polyglot Notebooks, allow me to summarize what they are.
The name Kusto came from Microsoft’s Azure Data Explorer product as a reference to Jacques Cousteau, a famous explorer and oceanographer.
Like Cousteau, Kusto was built to explore large bodies of data through a new query language. This query language was dubbed Kusto Query Language or KQL and was designed to search through Azure Data Explorer’s proprietary Kusto cluster format.
This makes KQL a very specialized tool that you may or may not use in your day-to-day development tasks. For those who need to be able to query Azure datastores using KQL, you may be keen to know that Kusto is a supported kernel option in Polyglot Notebooks.
