Update Vector

Overview

Vector update operations allow you to modify existing vector embeddings within your graph database. This functionality is essential for maintaining data accuracy, correcting vector embeddings, and adapting vector information as your application requirements evolve. Understanding vector update operations is crucial for effective vector management and ensuring your vector system remains current and relevant.

Key capabilities include:

Updating vector embeddings and dimensional data
Modifying vector metadata and properties
Maintaining data integrity during updates
Handling validation and error scenarios
Preserving vector relationships and associations

These operations support various use cases such as vector refinement, metadata updates, model migration, and maintaining consistency across your vector database.

Update Vector

Update an existing vector using PUT: /v1.0/tenants/{tenant-guid}/vectors/{vector-guid}. This endpoint allows you to modify the vector embeddings, metadata, and other properties of a specific vector while preserving its unique identifier and maintaining its associations with nodes or edges.

curl --location --request PUT 'http://localhost:8701/v1.0/tenants/00000000-0000-0000-0000-000000000000/vectors/00000000-0000-0000-0000-000000000000' \
--header 'content-type: application/json' \
--header 'Authorization: ••••••' \
--data '{
    "GraphGUID": "00000000-0000-0000-0000-000000000000",
    "NodeGUID": null,
    "EdgeGUID": null,
    "Model": "all-MiniLM-L6-v2",
    "Dimensionality": 384,
    "Content": "test",
    "Vectors": [
        0.1,
        0.2,
        0.3
    ]
}'

import { LiteGraphSdk } from "litegraphdb";

var api = new LiteGraphSdk(

const updateVector = async () => {
  try {
    const data = await api.Vector.update({

    console.log(data, "check data");
  } catch (err) {

Next Steps

After successfully updating vectors, consider these next actions:

Verify Changes: Read the updated vector to confirm changes were applied correctly
Update Dependencies: Check if any dependent systems need to be notified of changes
Monitor Impact: Track how vector updates affect related operations and queries
Document Changes: Maintain documentation of vector modification history
Optimize Performance: Review update patterns for potential performance improvements
