MB-68591: GPU-Accelerated Vector Search

[CascadingRadium]

• Add a flag: gpu to indicate whether the vector field must use GPUs for indexing/searching.
• Requires:
  • [v17] MB-68591: GPU-Accelerated Vector Search zapx#342
  • MB-67052: Add GPU bindings go-faiss#46
  • [v17] MB-68591: Add GPU Field Indexing Option bleve_index_api#77
  • Add an API to retrieve the amount of free memory in a GPU faiss#59

Pull Request Overview

This PR adds GPU acceleration support for vector field indexing and searching. The changes enable users to specify whether GPU should be used for vector operations through a new configuration field.

Key changes:

• Added GPU boolean field to FieldMapping struct for configuration
• Extended vector field constructors to accept and store GPU parameter
• Added GPU() getter method to VectorField for accessing the GPU configuration

document/field_vector_base64.go:163

• VectorBase64Field is missing a GPU() method to match the pattern of delegating VectorField interface methods. Since VectorBase64Field already exposes other VectorField methods like IndexOptimizedFor(), Similarity(), Dims(), and Vector(), it should also expose the GPU() method for API consistency. Add the following method after line 163:\n\ngo\nfunc (n *VectorBase64Field) GPU() bool {\n\treturn n.vectorField.GPU()\n}\n

func (n *VectorBase64Field) IndexOptimizedFor() string {
	return n.vectorField.IndexOptimizedFor()
}
