Update records in a Kusto Database (public preview)

Published date: February 20, 2024

Kusto databases, either in Azure Data Explorer or in Fabric KQL Database, are optimize for append ingestion.

In recent years, we've introduce the .delete command allowing you to selectively delete records.

Today we are introducing the .update command.  This command allows you to update records by deleting existing records and appending new ones in a single transaction.

We believe this new command gives you an alternative for your data pipelines.  Many loading scenarios involve updating records.  For instance, ingesting new data in a staging table to then update the records of a main table with those new records.  This is now possible with the .update command.

The command is in public preview and we are looking forward for your feedback!
