ICache will eventually replace the existing cache access functions on FDerivedDataCacheInterface. The notable differences relative to the existing interface are: - It is asynchronous with completion callbacks by default, and allows waiting when necessary. - It allows batch requests containing multiple cache records by default. - It uses a structured cache key made up of a bucket name and a hash. - It supports prioritization and cancellation of requests. - It supports structured cache records with metadata. - It supports attachments to allow multi-part cache records. - It uses a typed request object instead of an opaque integer handle. - It provides cache policy flags to control how to query and store cache records, and which parts of a cache record to fetch. This initial implementation of ICache is totally synchronous and uses the existing cache backends for storage. #rb Zousar.Shaker [CL 15152247 by Devin Doucette in ue5-main branch]
