[<CommonParameters>] Description
This cmdlet contains more than one parameter set. You may only use parameters from one parameter set and you may not combine parameters from different parameter sets. For more information about how to use parameter sets, see Cmdlet parameter sets.
Use the Split-SPScaleOutDatabase cmdlet to move a specified percentage of partitions from a source database to an existing target database or to a new database that you create with the specified parameters.

Examples
---------------EXAMPLE 1---------------
$databases = Get-SPScaleOutDatabase -ServiceApplication $serviceApplication
$database = $databases[0]
Split-SPScaleOutDatabase -NewDatabaseName Database2 -NewDatabaseServer MyDatabaseServer -SourceDatabase $database -SourceServiceApplication $serviceApplication -SourcePercentage 30This example creates a new scale-out database named Database2 on the MyDatabaseServer database server in the given service application.
The example also moves 30% of the data from the upper side of the data range in the first scale-out database of the given service application.
---------------EXAMPLE 2---------------
$ssa = Get-SPEnterpriseSearchServiceApplication
$newReportingDb = "Search_AnalyticsReporting2"
$reportingDb = Get-SPScaleOutDatabase -SearchApplication $ssa
Split-SPServerScaleOutDatabase -SourceServiceApplication $ssa -SourceDatabase $reportingDb -NewDatabaseName $newReportingDb -SourcePercentage 33This example scales out the Search Analytics database, moving 33% of data to the new databases.
Parameters
-AssignmentCollection
Manages objects for the purpose of proper disposal. Use of objects, such as SPWeb or SPSite, can use large amounts of memory and use of these objects in Windows PowerShell scripts requires proper memory management. Using the SPAssignment object, you can assign objects to a variable and dispose of the objects after they are needed to free up memory. When SPWeb, SPSite, or SPSiteAdministration objects are used, the objects are automatically disposed of if an assignment collection or the Global parameter is not used.
When the Global parameter is used, all objects are contained in the global store.
If objects are not immediately used, or disposed of by using the Stop-SPAssignment command, an out-of-memory scenario can occur.
