DDC in UE5.6

Development Pipeline & Plugins

Hi,

I’m curious about the current state of the various DDC stores in UE 5.6.

I’m aware of the following DDC stores with Horde Storage being a recent discovery.

  1. CloudDDC
  2. Zen Shared Server
  3. Zen Local Server
  4. Horde Storage

For a AAA studio, this is my current understanding of the DDC infrastructure:

For a physical studio location:

CloudDDC -> Shared Zen -> Local Zen

For a remote developer:

CloudDDC -> Local Zen

For a horde cloud build farm:

CloudDDC -> Shared Zen

I’m curious about how Horde Storage fits into these scenarios.

Thanks!

Hello!

Horde Storage is the system where the CI\CD tasks store their artefacts (logs and other). It does not store DDC related data.

You can find the up to date information on it in the following files:

  • Engine\Source\Programs\Horde\Docs\Config\Storage.md
  • Engine\Source\Programs\Horde\Docs\Internals\StorageArchitecture.md

Regards,

Martin
