If you’re really in a hurry, or if space on your Excel 2011 for Mac worksheet is at a premium and you want a quick visual representation of your data, sparklines are worth investigating. It only takes a few seconds to make sparklines. Here’s what to do:

  1. Select the data range.

    Don’t select any column or row headers in your data range — just the actual data.

  2. On the Ribbon’s Charts tab, find the Insert Sparklines group and choose a sparkline style.

    You get three choices for sparkline styles:

    • Line: Displays a mini-line chart of your data in a cell.

    • Column: Displays a mini-column chart of your series.

    • Win-Loss: Displays a bar above the cell’s midline for positive numbers, or a bar below the midpoint for negative numbers.

    After you choose a sparkline style, the Insert Sparklines dialog.

  3. Drag over the empty cells that you want to display your sparklines.

    Usually you want an adjoining range of empty cells.

  4. Click OK to close the Insert Sparklines dialog.

    Your sparklines display.

Now you have sparklines, but the rows are too skinny to display them properly. You need to increase the row height and center the text in the cells. Here’s what to do:

  1. Drag over the row numbers to select the rows you want to format.

    As you drag up or down to select a set of entire rows, the mouse cursor should be a right-pointing arrow.

  2. Drag any divider between two row numbers down within the selected rows to increase the row height.

    As you drag, the mouse cursor is a double-pointed arrow, and the row height displays as you drag. All selected rows heights are increased at once.

  3. Reselect the data range.

  4. On the Ribbon’s Home tab, go to the Alignment group and click Align Text Middle.

Notice that when you select a sparkline cell or cell range, the corresponding data lights up in your data range, and if you look up at the Ribbon, there’s a Sparklines tab you can click.

Spark is free for individual users, yet it makes money by offering Premium plans for teams. Spark is fully GDPR compliant, and to make everything as safe as possible, we encrypt all your data and rely on the secure cloud infrastructure provided by Google Cloud.

Apache Spark is a parallel processing framework that supports in-memory processing to boost the performance of big-data analytic applications. Apache Spark in Azure HDInsight is the Microsoft implementation of Apache Spark in the cloud. HDInsight makes it easier to create and configure a Spark cluster in Azure. Spark clusters in HDInsight are compatible with Azure Storage and Azure Data Lake Storage. So you can use HDInsight Spark clusters to process your data stored in Azure. For the components and the versioning information, see Apache Hadoop components and versions in Azure HDInsight.

What is Apache Spark?

Spark provides primitives for in-memory cluster computing. A Spark job can load and cache data into memory and query it repeatedly. In-memory computing is much faster than disk-based applications, such as Hadoop, which shares data through Hadoop distributed file system (HDFS). Spark also integrates into the Scala programming language to let you manipulate distributed data sets like local collections. There's no need to structure everything as map and reduce operations.

Spark clusters in HDInsight offer a fully managed Spark service. Microsoft office for macbook air student. Benefits of creating a Spark cluster in HDInsight are listed here.

FeatureDescription
Ease creationYou can create a new Spark cluster in HDInsight in minutes using the Azure portal, Azure PowerShell, or the HDInsight .NET SDK. See Get started with Apache Spark cluster in HDInsight.
Ease of useSpark cluster in HDInsight include Jupyter and Apache Zeppelin notebooks. You can use these notebooks for interactive data processing and visualization. See Use Apache Zeppelin notebooks with Apache Spark and Load data and run queries on an Apache Spark cluster.
REST APIsSpark clusters in HDInsight include Apache Livy, a REST API-based Spark job server to remotely submit and monitor jobs. See Use Apache Spark REST API to submit remote jobs to an HDInsight Spark cluster.
Support for Azure Data Lake StorageSpark clusters in HDInsight can use Azure Data Lake Storage as both the primary storage or additional storage. For more information on Data Lake Storage, see Overview of Azure Data Lake Storage.
Integration with Azure servicesSpark cluster in HDInsight comes with a connector to Azure Event Hubs. You can build streaming applications using the Event Hubs, in addition to Apache Kafka, which is already available as part of Spark.
Support for ML ServerSupport for ML Server in HDInsight is provided as the ML Services cluster type. You can set up an ML Services cluster to run distributed R computations with the speeds promised with a Spark cluster. For more information, see What is ML Services in Azure HDInsight.
Integration with third-party IDEsHDInsight provides several IDE plugins that are useful to create and submit applications to an HDInsight Spark cluster. For more information, see Use Azure Toolkit for IntelliJ IDEA, Use Spark & Hive Tools for VSCode, and Use Azure Toolkit for Eclipse.
Concurrent QueriesSpark clusters in HDInsight support concurrent queries. This capability enables multiple queries from one user or multiple queries from various users and applications to share the same cluster resources.
Caching on SSDsYou can choose to cache data either in memory or in SSDs attached to the cluster nodes. Caching in memory provides the best query performance but could be expensive. Caching in SSDs provides a great option for improving query performance without the need to create a cluster of a size that is required to fit the entire dataset in memory. See Improve performance of Apache Spark workloads using Azure HDInsight IO Cache.
Integration with BI ToolsSpark clusters in HDInsight provide connectors for BI tools such as Power BI for data analytics.
Pre-loaded Anaconda librariesSpark clusters in HDInsight come with Anaconda libraries pre-installed. Anaconda provides close to 200 libraries for machine learning, data analysis, visualization, and so on.
ScalabilityHDInsight allows you to change the number of cluster nodes dynamically with the Autoscale feature. See Automatically scale Azure HDInsight clusters. Also, Spark clusters can be dropped with no loss of data since all the data is stored in Azure Storage or Data Lake Storage.
SLASpark clusters in HDInsight come with 24/7 support and an SLA of 99.9% up-time.

Apache Spark clusters in HDInsight include the following components that are available on the clusters by default.

  • Spark Core. Includes Spark Core, Spark SQL, Spark streaming APIs, GraphX, and MLlib.

Spark clusters in HDInsight also provide an ODBC driver for connectivity to Spark clusters in HDInsight from BI tools such as Microsoft Power BI.

Spark cluster architecture

It's easy to understand the components of Spark by understanding how Spark runs on HDInsight clusters.

Spark applications run as independent sets of processes on a cluster, coordinated by the SparkContext object in your main program (called the driver program).

The SparkContext can connect to several types of cluster managers, which allocate resources across applications. These cluster managers include Apache Mesos, Apache Hadoop YARN, or the Spark cluster manager. In HDInsight, Spark runs using the YARN cluster manager. Once connected, Spark acquires executors on workers nodes in the cluster, which are processes that run computations and store data for your application. Next, it sends your application code (defined by JAR or Python files passed to SparkContext) to the executors. Finally, SparkContext sends tasks to the executors to run.

The SparkContext runs the user's main function and executes the various parallel operations on the worker nodes. Then, the SparkContext collects the results of the operations. The worker nodes read and write data from and to the Hadoop distributed file system. The worker nodes also cache transformed data in-memory as Resilient Distributed Datasets (RDDs).

The SparkContext connects to the Spark master and is responsible for converting an application to a directed graph (DAG) of individual tasks that get executed within an executor process on the worker nodes. Each application gets its own executor processes, which stay up for the duration of the whole application and run tasks in multiple threads.

Spark in HDInsight use cases

Spark clusters in HDInsight enable the following key scenarios:

Interactive data analysis and BI

Apache Spark in HDInsight stores data in Azure Storage or Azure Data Lake Storage. Business experts and key decision makers can analyze and build reports over that data and use Microsoft Power BI to build interactive reports from the analyzed data. Analysts can start from unstructured/semi structured data in cluster storage, define a schema for the data using notebooks, and then build data models using Microsoft Power BI. Spark clusters in HDInsight also support a number of third-party BI tools such as Tableau making it easier for data analysts, business experts, and key decision makers.

Spark Machine Learning

Microsoft

Apache Spark comes with MLlib, a machine learning library built on top of Spark that you can use from a Spark cluster in HDInsight. Spark cluster in HDInsight also includes Anaconda, a Python distribution with different kinds of packages for machine learning. Couple this with a built-in support for Jupyter and Zeppelin notebooks, and you have an environment for creating machine learning applications.

Spark streaming and real-time data analysis

Spark clusters in HDInsight offer a rich support for building real-time analytics solutions. While Spark already has connectors to ingest data from many sources like Kafka, Flume, Twitter, ZeroMQ, or TCP sockets, Spark in HDInsight adds first-class support for ingesting data from Azure Event Hubs. Event Hubs is the most widely used queuing service on Azure. Having an out-of-the-box support for Event Hubs makes Spark clusters in HDInsight an ideal platform for building real-time analytics pipeline.
