-------------------------------------------
Summary: Explore using FlatVectorsWriter for DenseVectorsWriter's
stored=true
Key: SOLR-17950
URL: https://issues.apache.org/jira/browse/SOLR-17950
Project: Solr
Issue Type: Improvement
Reporter: Ishan Chattopadhyaya
Today, when indexed=true, all vectors are written to a FlatVectorsWriter and a
HNSW graph is built using that. When stored=true, a regular stored field is
built using that. For a large vector index, it is wasteful to store raw vectors
in two places. Can we retrieve the vectors from the flat vectors index instead
of the stored fields to save on disk space and indexing time?
