Best practices for the Kusto Data library
Applies to: ✅ Microsoft Fabric ✅ Azure Data Explorer
This article explains the best practices for working with the Kusto Data library.
Use a single client instance
The Kusto client providers are designed for concurrent use by multiple threads, and they cache information retrieved during the initial contact with your database. To optimize performance, we recommend reusing a single client instance rather than creating a new one for each request.
Specify the database parameter
The default database property in the Kusto client provider isn't thread-safe. We recommend that you set this property on creation and refrain from altering it afterward. If a single client is used to send requests to multiple databases, use methods that accept a database parameter to specify the desired database.
Dispose of the client and request results
Although the Kusto client object is designed for use with multiple requests, it should be disposed of when it's no longer needed to send more requests. Likewise, request results objects should be disposed of once they've fulfilled their purpose. The correct disposal of these objects is key for maintaining scalability, as they retain essential network resources until they're explicitly disposed of or subjected to garbage collection.
