Because query execution performance critically depends on this choice, join ordering lies at the core of query optimization. Traditional approaches cast this problem as a discrete combinatorial search over binary trees guided by a cost model, but they have trade-offs between effectiveness and efficiency. We show that when the cost model is differentiable, query plans can be continuously relaxed into a soft adjacency matrix that represents a ","authors_text":"Maribel Acosta, Tim Schwabe","cross_cats":["cs.LG"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DB","submitted_at":"2025-11-18T13:24:28Z","title":"Gradient-Based Join Ordering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2511.14482","kind":"arxiv","version":2},"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":"sha256:500845278a662f0c7c202ddc2f7e7ef1ce8795775e64d8a21e2ac006d7601e39","target":"record","created_at":"2026-05-20T00:00:28Z","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":"680cfdbded51ae53c53720c8f33daa5690a14b769d939d2a8ffbb210615f53c3","cross_cats_sorted":["cs.LG"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.DB","submitted_at":"2025-11-18T13:24:28Z","title_canon_sha256":"b2283f5c48be1ef01be66da6867643737e769a7558046f69add946d40eaea124"},"schema_version":"1.0","source":{"id":"2511.14482","kind":"arxiv","version":2}},"canonical_sha256":"ad7ce20f5c9dac533c777bc298f29354e41ba6562ec2b586fd25b892fcb723cb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ad7ce20f5c9dac533c777bc298f29354e41ba6562ec2b586fd25b892fcb723cb","first_computed_at":"2026-05-20T00:00:28.083859Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-20T00:00:28.083859Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0GXw8yWhWVC90WdwKHhs7K7ld3nZsF8VR/c6KgmGRs2UJMsUWgJbd8yYL98XL+WoKJKmcH1F213jv01jVmVZDQ==","signature_status":"signed_v1","signed_at":"2026-05-20T00:00:28.084633Z","signed_message":"canonical_sha256_bytes"},"source_id":"2511.14482","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:500845278a662f0c7c202ddc2f7e7ef1ce8795775e64d8a21e2ac006d7601e39","sha256:a96790532420d6872c8d21040357d8beb6a38ceed837d879ca6a54c45e8a4a34"],"state_sha256":"8a6d3af813936a9f7e06e33edb8d3c31c14d0501cf73c65b9fc35620d88f1e16"}
