+1 I am biased because DiskANN is from Microsoft Research but it's a good library/algorithm ________________________________ From: Mike Adamson <madam...@datastax.com> Sent: Wednesday, September 20, 2023 8:58 AM To: dev <dev@cassandra.apache.org> Subject: [EXTERNAL] [DISCUSS] Add JVector as a dependency for CEP-30
You don't often get email from madam...@datastax.com. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> The original patch for CEP-30 brought several modified Lucene classes in-tree to implement the concurrent HNSW graph used by the vector index. These classes are now being replaced with the io.github.jbellis.jvector library, which contains an improved diskANN implementation for the on-disk graph format. The repo for this library is here: https://github.com/jbellis/jvector. The library does not replace any code used by SAI or other parts of the codebase and is used solely by the vector index. I would welcome any feedback on this change. -- [DataStax Logo Square]<https://www.datastax.com/> Mike Adamson Engineering +1 650 389 6000<tel:16503896000> | datastax.com<https://www.datastax.com/> Find DataStax Online: [LinkedIn Logo] <https://urldefense.proofpoint.com/v2/url?u=https-3A__www.linkedin.com_company_datastax&d=DwMFaQ&c=adz96Xi0w1RHqtPMowiL2g&r=IFj3MdIKYLLXIUhYdUGB0cTzTlxyCb7_VUmICBaYilU&m=uHzE4WhPViSF0rsjSxKhfwGDU1Bo7USObSc_aIcgelo&s=akx0E6l2bnTjOvA-YxtonbW0M4b6bNg4nRwmcHNDo4Q&e=> [Facebook Logo] <https://urldefense.proofpoint.com/v2/url?u=https-3A__www.facebook.com_datastax&d=DwMFaQ&c=adz96Xi0w1RHqtPMowiL2g&r=IFj3MdIKYLLXIUhYdUGB0cTzTlxyCb7_VUmICBaYilU&m=uHzE4WhPViSF0rsjSxKhfwGDU1Bo7USObSc_aIcgelo&s=ncMlB41-6hHuqx-EhnM83-KVtjMegQ9c2l2zDzHAxiU&e=> [Twitter Logo] <https://twitter.com/DataStax> [RSS Feed] <https://www.datastax.com/blog/rss.xml> [Github Logo] <https://github.com/datastax>
