Blob & Document Storage

Redwood supports traditional blob storage; blobs are just files/documents with any structure/format. If you want to simply persist USaveGames or any other larger files (i.e. larger images, documents, videos, etc.; think megabytes in size), this storage mechanism is better than using the database.

Unreal Interface​

There are a few easy-to-use functions in the URedwoodServerGameSubsystem to read/write data to the blob storage, including Blueprint-friendly latent nodes.

  • GetBlob - Read a blob from storage; returns a byte array
  • PutBlob - Write a blob to storage; takes a byte array
  • GetSaveGame - Read a USaveGame from the storage
  • PutSaveGame - Write a USaveGame to the storage

You don't have to do anything special with your SaveGame classes; they will be serialized and deserialized automatically.

Providers​

Redwood supports multiple blob storage providers; read more about them here.
