Data Pipelines and Filter Chaining

Warning ⚠️: New Docs Available

These are old docs and we haven't found the time to completely move them. You will find comprehensive new docs on docs.2sxc.org.

Some basics

1.  Data is stored in the database...
2. ...and is cached in Memory on the web server
3. When you need data, you request a DataSource from the cache...
4. ...and using some filters (usually Filter-DataSources) request a subset of all data
5. These pipeline-pieces can also be "chained" so you can first filter by type, then by Gender and finally sort by last-name

This is basically how it works (needs Razor):

// A source which can filter by Content-Type (EntityType)

var allAuthors = CreateSource<ToSic.Eav.DataSources.EntityTypeFilter>();

allAuthors.TypeName = "Authors";
