… In this section, we first introduce the basic pipeline design of the proposed compaction
engine. Then we present several important optimization modules to improve the …

… compaction) in LSM-tree key-value stores improves the write efficiency, and some lazy
compaction … we propose a novel Lower-level Driven Compaction (LDC) method which breaks the …

… In this paper, we argue that LSM-tree compaction has serious CPU overhead on fast …
compaction can be bounded by the data-intensive compression, and multi-threaded compaction …

… The write ampliication can be improved when we apply the cross-leveled compaction but
the pipelined compaction in PStore. We design experiments to explore this phenomenon. We …

… Additionally, We design two SSDGPU data transfer mechanisms, the Pipeline mechanism, …
any LSM-Tree storage system. Compared to CPUbased method and LUDA, our compaction …

… [26], but this scheme increases the number of tasks when compaction is kicked in, leading
to a high resource cost. The pipelined compaction [45] is a pipelined merge mechanism, …

… the flush and compaction operations in the LSM-tree. Because … when a flush or compaction
is executed in the LSM-tree, record … learning pipeline coupled with DBMS in our future work. …

… 7 CONCLUSION In this paper, we argue that LSM-tree compaction has serious CPU and
network overhead on high-speed disaggregated storage. With ine-grained breakdown, we ind …
