take operator

Return up to the specified number of rows.

T | take 5

There is no guarantee which records are returned, unless the source data is sorted.

Syntax

take NumberOfRows limit NumberOfRows

(take and limit are synonyms.)

Notes

take is a simple, quick, and efficient way to view a small sample of records when browsing data interactively, but be aware that it doesn't guarantee any consistency in its results when executing multiple times, even if the data set hasn't changed.

Even is the number of rows returned by the query is not explicitly limited by the query (no take operator is used), Kusto limits that number by default. Please see Kusto query limits for details.

Does Kusto support paging of query results?

Kusto doesn't provide a built-in paging mechanism.

Kusto is a complex service that continuously optimizes the data it stores to provide excellent query performance over huge data sets. While paging is a useful mechanism for stateless clients with limited resources, it shifts the burden to the backend service which has to track client state information. Subsequently, the performance and scalability of the backend service is severely limited.

For paging support implement one of the following features:

  • Exporting the result of a query to an external storage and paging through the generated data.

  • Writing a middle-tier application that provides a stateful paging API by caching the results of a Kusto query.
