Recently, many learned query optimizers (LQOs) have demonstrated significant performance improvements over traditional optimizers. However, most of them operate under a limited assumption: a static query environment. This limitation prevents them from effectively handling complex, dynamic query environments in real-world scenarios. Extensive retraining can lead to the well-known catastrophic forgetting problem, which reduces the LQO generalizability over time. In this paper, we address this limitation and introduce LIMAO (Li","authors_text":"Ibrahim Sabek, Qihan Zhang, Shaolin Xie","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2025-06-30T18:58:20Z","title":"LIMAO: A Framework for Lifelong Modular Learned Query Optimization"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.00188","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:d99d6e426655c469c81ee87956cb707bfea1570e3f2fc586208c2687eaea7c6a","target":"record","created_at":"2026-07-05T11:29:38Z","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":"e974acbad32ae61363433f2a848b9d84a94342dbbded6c00ff446823f2ca123b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DB","submitted_at":"2025-06-30T18:58:20Z","title_canon_sha256":"af0b5f93a51f1c38ee5bd1ca25aebfca5ed17fe0919f0e3f7e91c59ffbaecf9c"},"schema_version":"1.0","source":{"id":"2507.00188","kind":"arxiv","version":1}},"canonical_sha256":"aa2dfbe82b9968ab3596c5967cc33bf546aa7342cb9511588a9028cdc05a7542","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"aa2dfbe82b9968ab3596c5967cc33bf546aa7342cb9511588a9028cdc05a7542","first_computed_at":"2026-07-05T11:29:38.808977Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:29:38.808977Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HkwXKNdt8zS0AKsRGmpgNIwg2W1qUQCRiViSMukPFMhOvlTaAiJ1vKvH3F5kptkPtOGpWbQkuOPEG+VoRg/dBg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:29:38.809563Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.00188","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d99d6e426655c469c81ee87956cb707bfea1570e3f2fc586208c2687eaea7c6a","sha256:4687b90d7cb8ee161ffd1deeee2cae2d543ed13e20c94e8498dc15069453df66"],"state_sha256":"4f1050cb0ecf8ef49ae91828ed13b50b162d4ca40a65cf0d49aa5dd6d363dbe2"}
