Online Deduplication for Databases
Summary: dbDedup is a similarity-based online dedup scheme for DBMSs using byte-level delta encoding of records. Single-pass encoding integrates with storage and oplog, delivering up to 37x storage and 61x replication reductions with negligible throughput. (summarized by gpt-5-nano on Feb 09 2026)
