Expand description

Aggregate statistics for the BlockDeduplicator.

Note: re-exported as BddDeduplicationStats in lib.rs.

Fields§

§total_chunks: u64

Total logical chunk references across all live objects (including duplicates).

§unique_chunks: u64

Number of physically distinct chunks stored on disk.

§duplicate_chunks: u64

Logical references that point to already-stored chunks (total - unique).

§bytes_before: u64

Total raw bytes ingested via store_object calls.

§bytes_after: u64

Physical bytes currently occupying the chunk store.

§dedup_ratio: f64

Fraction of bytes saved by deduplication: 1 - (bytes_after / bytes_before). Range [0.0, 1.0]; higher is better.

§compression_ratio: f64

Ratio bytes_before / bytes_after. Values > 1.0 mean space was saved.
