  • update knn search request syntax, to enable users to supply search-time parameters,
    using which they can control the latency v/s recall tradeoff.

  • Supported parameters are

    • ivf_nprobe_pct
    • ivf_max_codes_pct
  • These parameters will be applied to those segments which have faissIVFIndex

  • In future, to support other faiss Index classes (like hnsw), the list of
    supported knn search params can be extended.

search_knn.go Outdated
//
// For Faiss IVF index, supported search params are:
// - nprobe_pct : int // percentage of total clusters to search
// - max_codes_pct : float // percentage of total vectors to visit to do a query (across all clusters)

@moshaad7 Given that these are going to be applicable to IVF indexes only, should we force their names to indicate this as well - ivf_nprobe_pct & ivf_max_codes_pct.
