This week is going to be very technical. I’ve also learned something new by writing this post and I hop eyou will too. The Azure Data Explorer team has released a set of new functionality to help with clustering on data using a Log Reduce approach. The “old” approach Before the release described below - the ADX service had a good handfull of features to help with anomaly detection and clustering on semi structured data. [...]

In todays post I’ll dive into the choice between the options when creating the clusters for Azure Data Explorer. The underlying architecture for the Kusto/ADX clusters is build on virtual machines (VM) with specific configrations. Dev/test vs production When creating the clusters from the Azure portal, you are presented with 3 options when choosing the compute specification. The compute specification is the method of setting up the clusters for the specific workload you are planning to put on the Kusto cluster. [...]

// Learn Kusto - Week 2

Last week I tried to lay the foundation to understand the engine that supports and drives the Kusto language and the Azure Data Explorer. We learned that the engine is using Shards as a primary storage method and how the engine handles the queries and executes them. This week we’ll start at the beginning of the Kusto language and do some basic data discovery. The setup and demo data For you to be able to follow along, you have to set up your own Kusto demo environment. [...]
