DobLIX: A Dual-Objective Learned Index for Log-Structured Merge Trees
Summary: DobLIX: a dual-objective learned index for LSM trees that trains models to minimize both index lookup error and downstream on-disk data-access cost, addressing I/O-heavy lookups when index parts live on disk. Includes an RL tuner for online adaptation, yielding 1.19×–2.21× throughput gains in RocksDB while preserving write efficiency.
