However, in LSM-tree, random key-value queries can experience long latency and low throughput due to the interference from the compaction, a basic operation in the algorithm, to caching. LSM-tree relies on frequent compaction operations to merge data into a sorted structure. After a compaction, the original data are reorganized and written to other locations on the disk. As a result, the cached data are invalidated since their referencing addresse","authors_text":"Dejun Teng, Feng Chen, Lei Guo, Rubao Lee, Siyuan Ma, Xiaodong Zhang","cross_cats":["cs.DB"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-06-07T03:53:45Z","title":"Re-enabling high-speed caching for LSM-trees"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.02015","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:71bc3342d8125b72f899675dd281a5592b26e24da13413a1d33bb3ccd07ca3a9","target":"record","created_at":"2026-05-18T01:12:44Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"e05b86ff7351e91dafa919f1aa3ab421688ee6cf66504934264d0ceb849038d3","cross_cats_sorted":["cs.DB"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-06-07T03:53:45Z","title_canon_sha256":"0f944c340bc2858eae046c276e21f286d9534c565c95204d0b04990602f41cd3"},"schema_version":"1.0","source":{"id":"1606.02015","kind":"arxiv","version":1}},"canonical_sha256":"d8deec8214966b07e96715ba74a1b7fc06de5896800482ec4d1b39ebe9d3a98e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d8deec8214966b07e96715ba74a1b7fc06de5896800482ec4d1b39ebe9d3a98e","first_computed_at":"2026-05-18T01:12:44.827244Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:12:44.827244Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pMDofhEDF4AMKWwQIToJV4OiVpDup/9u9qKr2unxD7lxy9tbYgcLqkX765Dq4KhzSZVUiq1x2rDtPGDq5ajPAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:12:44.827622Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.02015","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:71bc3342d8125b72f899675dd281a5592b26e24da13413a1d33bb3ccd07ca3a9","sha256:ee7284397aa1cabc415ba27a8c47f6d3e89138c68fd9106849ad827869d5e964"],"state_sha256":"7ad44e54c58d4dc4677191627beb7c2aa4d636490bfb7999051872fc7b0c287c"}
