Summary: The ldb list_live_files_metadata command does not print any information about blob files currently. We would like to add this functionality. Note that list_live_files_metadata has two different modes of operation: the one shown above, which shows the LSM tree structure, and another one, which can be enabled using the flag --sort_by_filename and simply lists the files in numerical order regardless of level. We would like to show blob files in both modes. Changes: 1. Using GetAllColumnFamilyMetaData API instead of GetLiveFilesMetaData API for fetching live files data. Testing: 1. Created a sample rocksdb instance using dbbench command (this creates both SST and blob files) 2. Checked if the blob files are listed or not by using ldb commands.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples
See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/ and https://rocksdb.slack.com/
