Levi Tamasi 1b4be4cac9 BlobDB: ignore trivially moved files when updating the SST<->blob file mapping (#6381) ... Summary: BlobDB keeps track of the mapping between SSTs and blob files using the `OnFlushCompleted` and `OnCompactionCompleted` callbacks of the `EventListener` interface: upon receiving a flush notification, a link is added between the newly flushed SST and the corresponding blob file; for compactions, links are removed for the inputs and added for the outputs. The earlier code performed this link deletion and addition even for trivially moved files; the new code walks through the two lists together (in a fashion that's similar to merge sort) and skips such files. This should mitigate https://github.com/facebook/rocksdb/issues/6338, wherein an assertion is triggered with the earlier code when a compaction notification for a trivial move precedes the flush notification for the moved SST.
