Explorer is a rich desktop application that allows you to explore your data using Kusto query language. Install the Kusto. Explorer tool. If you use Chrome as your default browser, make sure to install the ClickOnce extension for Chrome:. You might find that using keyboard shortcuts enables you to perform operations faster than with the mouse. Take a look at this list of Kusto. Explorer keyboard shortcuts.
Explorer keeps track of what settings are used per unique set of columns. So when columns are reordered or removed, the data view is saved and will be reused whenever the data with the same columns is retrieved.
To reset the view to its defaults, in the View tab, select Reset View. The left pane of Kusto. Explorer shows all the cluster connections that the client is configured with.
For each cluster it shows the databases, tables, and attributes columns that they store. Explorer supports controlling the Connection panel from the query window. This is very useful for scripts. For example, starting a script file with a command that instructs Kusto. As usual, you'll have to run each line using F5 or similar:. When adding a new connection, the default security model used is AAD-Federated security, in which authentication is done through the Azure Active Directory using the default AAD user experience.
In some cases, you might need finer control over the authentication parameters than is available in AAD. If so, it's possible to expand the "Advanced: Connection Strings" edit box and provide a valid Kusto connection string value. For example, users who have presence in multiple AAD tenants sometimes need to use a particular "projection" of their identities to a specific AAD tenant. The domain name of the user is not necessarily the same as that of the tenant hosting the cluster. Explorer tries to "guess" the severity or verbosity level of each row in the results pane and color it accordingly.It is based on relational database management systems, supporting entities such as databases, tables, and columns, as well as providing complex analytics query operators such as calculated columns, searching and filtering or rows, group by-aggregates, joins.
As a Big Data service, Kusto handles structured, semi-structured e. JSON-like nested typesand unstructured free-text data equally well. The main way for users to interact with Kusto is by using one of the many client tools available for Kusto. While SQL queries to Kusto are supported, the primary means of interaction with Kusto is through the use of the Kusto query language to send data queries, and through the use of control commands to manage Kusto entities, discover metadata, etc.
Both queries and control commands are basically short textual "programs". A Kusto query is a read-only request to process Kusto data and return the results of this processing, without modifying the Kusto data or metadata. Kusto queries can use the SQL languageor the Kusto query language.
As an example for the latter, the following query counts how many rows in the Logs table have the value of the Level column equals the string Critical :. Queries cannot start with the dot.
Control commands are requests to Kusto to process and potentially modify data or metadata. For example, the following control command creates a new Kusto table with two columns, Level and Text :. Control commands have their own syntax which is not part of the Kusto query language syntax, although the two share many concepts.
In particular, control commands are distinguished from queries by having the first character in the text of the command be the dot. This distinction prevents many kinds of security attacks, simply because this prevents embedding control commands inside queries.
Not all control commands modify Kusto data or metadata. A large class of commands, the commands that start with.

But the issue turned out to be with the version of. Net Framework that I was running. The Kusto. Data package requires. Net Framework 4. When I had that installed, I was able to install and import the package, and also subsequently connect to the intended Kusto cluster and read data. This is the snippet that worked for me:.

Common; using Kusto.Kusto connection strings can provide the information necessary for a Kusto client application to establish a connection to a Kusto service endpoint. Kusto connection strings are modeled after the ADO. NET connection strings. Programmatically, Kusto connection strings can be parsed and manipulated by the C Kusto. KustoConnectionStringBuilder class. This class validates all connection strings and generates a runtime exception if validation fails.
This functionality is present in all flavors of Kusto SDK.What Is Azure? - Microsoft Azure Tutorial For Beginners - Microsoft Azure Training - Simplilearn
The following table lists all the properties you can specify in a Kusto connection string. It lists programmatic names which is the name of the property in the Kusto.

Azure Data Explorer is a fast, fully managed data analytics service for real-time analysis on large volumes of data. The Azure Data Explorer connector for Spark is an open source project that can run on any Spark cluster.
Getting started with Kusto
It implements data source and data sink for moving data across Azure Data Explorer and Spark clusters. Using Azure Data Explorer and Apache Spark, you can build fast and scalable applications targeting data driven scenarios. With the connector, Azure Data Explorer becomes a valid data store for standard Spark source and sink operations, such as write, read, and writeStream. You can write to Azure Data Explorer in either batch or streaming mode.
Reading from Azure Data Explorer supports column pruning and predicate pushdown, which filters the data in Azure Data Explorer, reducing the volume of transferred data. Although some of the examples below refer to an Azure Databricks Spark cluster, Azure Data Explorer Spark connector does not take direct dependencies on Databricks or any other Spark distribution.
This step is optional. If you are using pre-built libraries go to Spark cluster setup. Refer to this source for building the Spark Connector. For more information, see connector usage. It's recommended to use the latest Azure Data Explorer Spark connector release when performing the following steps. Configure the following Spark cluster settings, based on Azure Databricks cluster using Spark 2. Azure AD application authentication is the simplest and most common authentication method and is recommended for the Azure Data Explorer Spark connector.
For more information on Azure Data Explorer principal roles, see role-based authorization. For managing security roles, see security roles management. When reading small amounts of datadefine the data query:. Optional: If you provide the transient blob storage and not Azure Data Explorer the blobs are created are under the caller's responsibility.
This includes provisioning the storage, rotating access keys, and deleting transient artifacts. The KustoBlobStorageUtils module contains helper functions for deleting blobs based on either account and container coordinates and account credentials, or a full SAS URL with write, read and list permissions. When the corresponding RDD is no longer needed, each transaction stores transient blob artifacts in a separate directory.
This directory is captured as part of read-transaction information logs reported on the Spark Driver node. In the example above, the Key Vault isn't accessed using the connector interface; a simpler method of using the Databricks secrets is used.
If you provide the transient blob storage, read from Azure Data Explorer as follows:.Released: Mar 3, View statistics for this project via Libraries. Tags kusto, wrapper, client, library.
