Azure Data Lake Explorer

Posted on  by



Azure Data Explorer integrates with Azure Blob Storage and Azure Data Lake Storage (Gen1 and Gen2), providing fast, cached, and indexed access to data stored in external storage. You can analyze and query data without prior ingestion into Azure Data Explorer. You can also query across ingested and uningested external data simultaneously. Azure Storage Explorer not only offers a traditional desktop explorer GUI for dragging, uploading, downloading, copying and moving your ADLS folders and files, but also provides a unified developer experiences of displaying file properties, viewing folder statistics and adding quick access.

This article shows you how to use Azure Storage Explorer to create and manage directories and files in storage accounts that has hierarchical namespace (HNS) enabled.

Prerequisites

  • An Azure subscription. See Get Azure free trial.

  • A storage account that has hierarchical namespace (HNS) enabled. Follow these instructions to create one. Slow download speed using ethernet cable on macbook pro 13 mid 2010.

  • Virtual dj home edition free download mac. Azure Storage Explorer installed on your local computer. To install Azure Storage Explorer for Windows, Macintosh, or Linux, see Azure Storage Explorer.

Note

Storage Explorer makes use of both the Blob (blob) & Data Lake Storage Gen2 (dfs) endpoints when working with Azure Data Lake Storage Gen2. If access to Azure Data Lake Storage Gen2 is configured using private endpoints, ensure that two private endpoints are created for the storage account: one with the target sub-resource blob and the other with the target sub-resource dfs.

Sign in to Storage Explorer

When you first start Storage Explorer, the Microsoft Azure Storage Explorer - Connect window appears. While Storage Explorer provides several ways to connect to storage accounts, only one way is currently supported for managing ACLs.

TaskPurpose
Add an Azure AccountRedirects you to your organization's sign-in page to authenticate you to Azure. Currently this is the only supported authentication method if you want to manage and set ACLs.
Use a connection string or shared access signature URICan be used to directly access a container or storage account with a SAS token or a shared connection string.
Use a storage account name and keyUse the storage account name and key of your storage account to connect to Azure storage.

Select Add an Azure Account and click Sign in.. Follow the on-screen prompts to sign into your Azure account.

When it completes connecting, Azure Storage Explorer loads with the Explorer tab shown. This view gives you insight to all of your Azure storage accounts as well as local storage configured through the Azurite storage emulator, Cosmos DB accounts, or Azure Stack environments.

Create a container

A container holds directories and files. To create one, expand the storage account you created in the proceeding step. Select Blob Containers, right-click, and select Create Blob Container. Enter the name for your container. See the Create a container section for a list of rules and restrictions on naming containers. When complete, press Enter to create the container. Once the container has been successfully created, it is displayed under the Blob Containers folder for the selected storage account.

Create a directory

To create a directory, select the container that you created in the proceeding step. In the container ribbon, choose the New Folder button. Enter the name for your directory. When complete, press Enter to create the directory. Once the directory has been successfully created, it appears in the editor window.

Upload blobs to the directory

On the directory ribbon, choose the Upload button. This operation gives you the option to upload a folder or a file.

Choose the files or folder to upload.

When you select OK, the files selected are queued to upload, each file is uploaded. When the upload is complete, the results are shown in the Activities window.

View blobs in a directory

In the Azure Storage Explorer application, select a directory under a storage account. Download solver studio for mac. The main pane shows a list of the blobs in the selected directory.

Download blobs

To download files by using Azure Storage Explorer, with a file selected, select Download from the ribbon. A file dialog opens and provides you the ability to enter a file name. Select Save to start the download of a file to the local location.

Azure Data Explorer With Data Lake

Azure Data Explorer is a fully-managed[1]big data analytics cloud platform[2][3] and). The project aim was to address Azure services' needs for fast and scalable log and telemetry analytics.

Azure

In 2016 it became the backend big-data and analytics service for Application Insights Analytics.[13]

The product was announced as a Public Preview product at the Microsoft Ignite 2018 conference,[14] and was announced as a generally available at the Microsoft Ignite conference of February 2019.[15]

On March 2021, 'Kusto EngineV3', Azure Data Explorer’s next generation storage and query engine, became generally available. It was designed to provide unparalleled performance for ingesting and querying telemetry, logs, and time series data. [16]

Features[edit]

Azure Data Explorer offers an optimized query language and visualizing options[17] of its data with a SQL-like language called KQL (Kusto Query Language.[18][19][20]).[7][8] KQL is used for querying only and unlike SQL, KQL can not update or delete data.[21]

Azure Data Explorer can ingest 200 MB per second per node.[14] Data Ingestion methods are pipelines and connectors to common services like Azure Event Grid or Azure Event Hub,[22] or programmatic ingestion using SDKs.

Data visualization can be achieved with tools like PowerBI[22][23] or Grafana.[24][25]

Design[edit]

Azure Data Explorer is a distributed database running on a cluster of compute nodes in Microsoft Azure. It is based on relational database management systems (RDBMS), supporting entities such as databases, tables, functions, and columns. It supports complex analytics query operators, such as calculated columns, searching and filtering or rows, group by-aggregates and joins.[26]

The engine service exposes a relational data model: At the top level (cluster) there is a collection of databases, each database contains a collection of tables and stored functions. Each table defines a schema (ordered list of typed fields).

In Azure Data Explorer, unlike a typical relational database management systems (RDBMS), there are no constraints like key uniqueness, primary and foreign key.[27] The necessary relationships are established at the query time.[28] The data in Azure Data Explorer generally follows this pattern:[29] Creating Database, Ingesting data, Query the database.
