- Added IRequestOwner::LaunchTask to launch a task as a request in the request owner.
- Renamed ExecuteInCacheThreadPool to LaunchTaskInCacheThreadPool.
- Made GCacheThreadPool private to one source file.
- Changed task scheduling throughout DDC to use these functions where appropriate.

- Legacy puts are now executing asynchronously.
- Memory cache now merges partial cache records.
- Memory cache is used to store data temporarily while it is being written by an async put.
- Expanded the deprecation of persisted boot/memory caches, which no longer offer the performance benefit that they used to.
- Fixed the pak file cache to skip data with a compressed size of over 2 GiB.

- FileSystem, Http, Pak, S3 use the ValueWithLegacyFallback mode by default, which cause them to fall back to searching for uncompressed data if compressed data is not found.
- FileSystem has been fixed to store up to 1 MiB of compressed data inline with the value package rather than separately in content-addressable storage.
- Pak has been optimized to have GetChunks only load the required region of the requested value, rather than the whole value.
- Pak has been changed to stop storing data inline in the record package, since it will end up in the same file anyway when stored separately.
- Pak will upgrade the compressor and compression level when a compressed pak file is requested. Default cache compression uses Oodle Mermaid VeryFast and will upgrade to Oodle Kraken Optimal2.
- Zen does not have compression enabled by default, pending deployment of a new version that stores compressed values to Horde Storage.
- Added a missing request barrier when saving uncompressed data as compressed.
Example reduction in file system cache size when cooking for Windows:
- CitySample dropped from 66.5 GiB to 21.8 GiB.
- Lyra dropped from 2.54 GiB to 672 MiB.
- ShooterGame dropped from 1.21 GiB to 380 MiB.
Example reduction in compressed pak file cache size when cooking for Windows:
- CitySample dropped from 22.3 GiB to 18.5 GiB.
- Lyra dropped from 691 MiB to 543 MiB.
- ShooterGame dropped from 387 MiB to 313 MiB.
