The extend operator adds a new column to the input result set, which does not have an index. In most cases, if the new column is set to be exactly the same as an existing table column that has an index, Kusto can automatically use the existing index. However, in some complex scenarios this propagation is not done.In this video, we are going to learn about "summarize" in the context of the Kusto Query Language (KQL).

This is easiest to summarize with an example: let myTable = datatable (Timestamp:datetime) [datetime(1910-06-11), datetime(1930-01-01), datetime(1997-06-25), I have start and end calculated columns which I have read from Ta Variables in KQL work similarly to CTEs in SQL, that is, they are a set of transformations that can be reused by calling the variable. The interesting bit is variables can be a scalar or a tabular value. ... summarize arg_max identified the row with the highest TotalInjuries value for each State and then returned the entire row (mind the asterisk).Summarizing the data makes it more meaningful. The Summarize operator does just what it suggests – it summarizes data. In deeper terms, it produces a table (in the results) that aggregates the content of the input table. As an example of this, use the following KQL query in the KQL Playground ( https://aka.ms/LADemo) to see the results. 5. if you want to have LocationId as one of the aggregation [I am trying to summarize my data monthly. Using something like ` biHere are some examples of KQL queries to help you Task 3: Analyze Results in KQL with the Summarize Operator. In this task, you will build KQL statements to aggregate data. Summarize groups the rows according to the by group columns, and calculates aggregations over each group. The following statement demonstrates the count() function, which returns a count of the group.
