Production - Ensure we detect and replay a failed txn involving blobs forward or backward at startup.Far future More options for blob directory structures (e.g. dirstorages bushy/chunky/lawn/flat). Make the ClientStorage support minimizing the blob cache. (Idea: LRU principle via mstat access time and a size-based threshold) currently). Make blobs able to efficiently consume existing files from the filesystemSavepoint support================= - A savepoint represents the whole state of the data at a certain point in time - Need special storage for blob savepointing (in the spirit of tmpstorage) - What belongs to the state of the data? - Data contained in files at that point in time - File handles are complex because they might be referred to from various places. We would have to introduce an abstraction layer to allow switching them around... Simpler solution: :
