The lookup operator optimizes the performance of queries where a fact table is enriched with data from a dimension table. It extends the fact table with values that are looked up in a dimension table. For best performance, the system by default assumes that the left table is the larger fact table, and the right table is the smaller dimension table.Here is the KQL query that I came up with and saved as a custom function. Suggestions for improvement are welcome! ... union (SecurityAlert // join to Entities IP pool | mv-expand parse_json(Entities) | project IPs = Entities["Address"] | where isnotempty(IPs) | distinct tostring(IPs)) // get only unique IPs | order by IPsIt corresponds to the use of an explicit state machine for correlation in traditional SIEMs using "Active Lists" or "reference sets." Therefore, the Azure Sentinel version avoids the state machine and is much simpler to build and maintain. In this post, I will describe implicit correlation rules and implementing them using the KQL operator join.

An aggregation function performs a calculation on a set of values, and returns a single value. These functions are used in conjunction with the summarize operator.

For scalar functions, see Scalar function types.%kql --conn To check the details of a specific connection, run the following command: %kql --conn <database-name>@<cluster-name> Query and visualize. Query data using the render operator and visualize data using the ploy.ly library. This query and visualization supplies an integrated experience that uses native KQL.Solution #2: Handle duplicate rows during query. Another option is to filter out the duplicate rows in the data during query. The arg_max() aggregated function can be used to filter out the duplicate records and return the last record based on the timestamp (or another column).
