Set statement

The set statement is used to set a request property for the duration of the query.

Request properties control how a query executes and returns results. They can be boolean flags, which are false by default, or have an integer value. A query may contain zero, one, or more set statements. Set statements affect only the tabular expression statements that trail them in the program order. Any two statements must be separated by a semicolon.

Request properties aren't formally a part of the Kusto Query Language and may be modified without being considered as a breaking language change.

If using a Kusto client library, request properties can be set using the ClientRequestProperties class of Kusto Data.
