Removes vectors from the index by their IDs. This operation permanently deletes the specified vectors and their associated data. 
func (e *EncryptedIndex) Delete(ctx context.Context, ids []string) error

​
Parameters

ParameterTypeDescription
ctxcontext.ContextContext for cancellation and timeouts
ids[]stringSlice of vector IDs to delete

​
Error Handling

  • Returns error if the API request fails due to network connectivity issues
  • Returns error if authentication fails (invalid API key)
  • Returns error if the encryption key is invalid for the specified index
  • Returns error if there are internal server errors during deletion
  • Returns error if the IDs slice is empty
  • The operation succeeds even if some IDs don’t exist in the index

Example Usage

package main

import (
    "context"
    "encoding/hex"
    "fmt"
    "log"

    "github.com/cyborginc/cyborgdb-go"
)

func main() {
    client, err := cyborgdb.NewClient("http://localhost:8000", "your-api-key")
    if err != nil {
        log.Fatal(err)
    }

    // Load an existing index
    indexKeyHex := "your-64-character-hex-key-here"
    indexKey, err := hex.DecodeString(indexKeyHex)
    if err != nil {
        log.Fatal(err)
    }

    index, err := client.LoadIndex(context.Background(), "my-vector-index", indexKey)
    if err != nil {
        log.Fatal(err)
    }

    // Delete specific vectors by ID
    ids := []string{"doc1", "doc2", "doc3"}

    err = index.Delete(context.Background(), ids)
    if err != nil {
        log.Fatalf("Delete failed: %v", err)
    }

    fmt.Printf("Successfully deleted %d vectors\n", len(ids))
}
