`s3vector_delete_vectors`

Delete vectors by keys from an Amazon S3 Vector index.

For complete teardown, run this node before s3vector_delete_index, then run s3vector_delete_bucket after every index in the bucket has been deleted.

Parameters

vector_bucket_namestringrequired*: Explicit bucket name that owns a named index.
bucketstringdefault no: Alias for vector_bucket_name.
index_namestringrequired*: Explicit target index name.
indexstringdefault no: Alias for index_name.
index_arnstringrequired*: Explicit self-contained alternative target.
keysarray<string>required: Keys to delete from the index.
keys_source_keystring: Context key containing string-array keys.
regionstringdefault AWS region chain: Override S3VECTORS_REGION, S3_REGION, AWS_REGION, or AWS_DEFAULT_REGION.
endpoint_urlstringdefault AWS_ENDPOINT_URL env var: Override the S3 Vectors service endpoint.
output_keystringdefault s3vector: Prefix for context output keys.

Target Resolution and Safety

Use exactly one explicit configured shape after interpolation: vector_bucket_name/bucket plus index_name/index, or index_arn by itself. Bucket ARN plus index name is not supported. Resource identifier environment variables are deliberately never consulted for vector deletion; region, endpoint, and AWS credentials may still come from the environment. Conflicting forms and non-string, incomplete, or blank targets fail before the AWS client is built.

Context Output

{output_key}_deleted_count — Number of keys submitted for deletion.
{output_key}_deleted_keys — Key list.
{output_key}_success — true on success.

Example

local flow = Flow.new("s3vector_delete_vectors_example")

flow:step("delete_vectors", nodes.s3vector_delete_vectors({
    vector_bucket_name = "ironflow-vectors-demo",
    index_name = "ironflow-demo-index",
    keys = { "doc-1", "doc-2" },
    output_key = "delete"
}))

return flow
