knowhere-v2.3.0

Release Notes

What's new?

• Sparse Index:
  • Introduced sparse vectors. Indexes SPARSE_WAND and SPARSE_INVERTED_INDEX are supported.
• GPU-based indexes:
  • Supported CAGRA, a GPU-based graph index from Nvidia.
  • Supported BRUTE_FORCE for GPU.
• Iterator:
  • Iterating approximately nearest vector is supported. A new API Interator is introduced for HNSW and IVF-series indexes.
  • SPARSE_WAND and SPARSE_INVERTED_INDEX also supports iterators.
• Multiple Data Types:
  • Knowhere now supports BF16 and FP16 as data type.
• Breaking Change:
  • knowhere::IndexFactory::Instance().Create<T>() now returns an expected<Index<IndexNode>> instead of Index<IndexNode>.
