Tall Arrays and
mapreduceon Spark® and Hadoop® clusters, and parallel pools
You can use Parallel Computing Toolbox™ to evaluate tall-array expressions in parallel using a parallel pool on your desktop. Using tall arrays allows you to run big data applications that do not fit in memory on your machine. You can also use Parallel Computing Toolbox to scale up tall-array processing by connecting to a parallel pool running on a MATLAB Parallel Server™ cluster. Alternatively, you can use a Spark enabled Hadoop cluster running MATLAB Parallel Server. For more information, see Big Data Workflow Using Tall Arrays and Datastores.
