how to condition split supporting case details information in ssis - ssis

Question

How many maximum cases are possible in conditional split Transformation in SSIS?

Answer 1

I don't know.
I know that using the below Biml, I was able to generate an SSIS package with a conditional split with 1024 output paths which went to their own, empty, Derived Column.
<Biml xmlns="http://schemas.varigence.com/biml.xsd">
<#int upperBound = 1023;#>
<Connections>
<OleDbConnection ConnectionString="Data Source=localhost\dev2014;Initial Catalog=tempdb;Provider=SQLNCLI11.1;Integrated Security=SSPI;Auto Translate=False;Packet Size=32767;" Name="Source" />
</Connections>
<Packages>
<Package Name="SO_50393307">
<Tasks>
<Dataflow Name="DFT CSPL POC">
<Transformations>
<OleDbSource Name="SRC Query" ConnectionName="Source">
<DirectInput>SELECT 1 AS Col1;</DirectInput>
</OleDbSource>
<ConditionalSplit Name="CSPL Boundary Test" >
<OutputPaths>
<# foreach (int indexer in System.Linq.Enumerable.Range(0, upperBound)){#>
<OutputPath Name="Repro_<#= indexer #>"><Expression><![CDATA[Col1 == <#= indexer #>]]></Expression></OutputPath>
<#}#>
</OutputPaths>
</ConditionalSplit>
<# foreach (int indexer in System.Linq.Enumerable.Range(0, upperBound)){#>
<DerivedColumns Name="DER Anchor <#= indexer #>">
<InputPath OutputPathName="CSPL Boundary Test.Repro_<#= indexer #>" />
</DerivedColumns>
<#}#>
</Transformations>
</Dataflow>
</Tasks>
</Package>
</Packages>
</Biml>
Now, just because I was able to generate that package doesn't mean that Visual Studio could edit the package. After an hour of letting VS2017 churn on opening it, I gave up.
It does however execute - took 7 seconds from the commandline.
