However the increasing volume of data to be stored has motivated the introduction of erasure codes, a storage efficient alternative to replication, particularly suited for archival in data centers, where old datasets (rarely accessed) can be erasure encoded, while replicas are maintained only for the latest data. Many recent works consider the design of new storage-centric erasure codes for improved repairability. In contrast, this paper addresses the migration from replication to en","authors_text":"Anwitaman Datta, Frederique Oggier, Lluis Pamies-Juarez","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2012-07-29T04:27:44Z","title":"RapidRAID: Pipelined Erasure Codes for Fast Data Archival in Distributed Storage Systems"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1207.6744","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":"sha256:8d8b61174ad0102d9828962faf43ad6cd525e2770489fa3b31adf0a0348638de","target":"record","created_at":"2026-05-18T03:49:32Z","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":"d9541737374ae6bf6e0e816248aec282693ccee83d75c4c45d636d508b93c704","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DC","submitted_at":"2012-07-29T04:27:44Z","title_canon_sha256":"c90988ff48d4976f620e208623dd2473e9bb706882cccc3ecdc2a8251ef918ba"},"schema_version":"1.0","source":{"id":"1207.6744","kind":"arxiv","version":2}},"canonical_sha256":"2095d0543311c0b5afeac324545c02f3bbe4734292baec70be5f4b48c8830114","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2095d0543311c0b5afeac324545c02f3bbe4734292baec70be5f4b48c8830114","first_computed_at":"2026-05-18T03:49:32.266736Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:49:32.266736Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CXQCtkupmeEPfeUyUAvK9Pe0x2J/M85cPkDahjawd+3fTn6vYDDp1YxCbO10sTmtbUdemKROnA90Bo6tnpxwBw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:49:32.267730Z","signed_message":"canonical_sha256_bytes"},"source_id":"1207.6744","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8d8b61174ad0102d9828962faf43ad6cd525e2770489fa3b31adf0a0348638de","sha256:d390446c288eade09e8852dcc03354044c411195ae2ad816ba3038af9a8cbb58"],"state_sha256":"4266ebec55c5504f3f0bb1412d4165fdc4d52187f8912de66176e36b14e83bca"}
