%SQL.VectorIndex.HNSWIndexer

Latest graph storage version number

The number of bi-directional links created for every new element during construction

A parameter that controls the number of layers in this graph

Inherited description: This callback method is invoked by the %New() method to provide notification that a new instance of an object is being created.

If this method returns an error then the object will not be created.

It is passed the arguments provided in the %New call. When customizing this method, override the arguments with whatever variables and types you expect to receive from %New(). For example, if you're going to call %New, passing 2 arguments, %OnNew's signature could be:

Method %OnNew(dob as %Date = "", name as %Name = "") as %Status If instead of returning a %Status code this returns an oref and this oref is a subclass of the current class then this oref will be the one returned to the caller of %New method.

Return a random positive integer based on the probability distribution described in the HNSW paper (https://arxiv.org/abs/1603.09320). Parameter: mL: controls the shape of the distribution. A larger mL results in more layers in the graph

Returns by reference the next nearest neighbor to i%Point and the distance between this neighbor to i%Point If the table is partitioned, this function expect these two properties being defined: i%PartitionKeys=$lb(partKey1,...,partKeyN) and %BucketID. In this case the returned id is the pRowID of the next nearest neighbor.
