fdc1cb43a6
Summary: The patch adds a new command line parameter --decode_blob_index to sst_dump. If this switch is specified, sst_dump prints blob indexes in a human readable format, printing the blob file number, offset, size, and expiration (if applicable) for blob references, and the blob value (and expiration) for inlined blobs. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5926 Test Plan: Used db_bench's BlobDB mode to generate SST files containing blob references with and without expiration, as well as inlined blobs with and without expiration (note: the latter are stored as plain values), and confirmed sst_dump correctly prints all four types of records.
