Implement optional index tags in create_index and configure_index

[jhamon]

Problem

Want to expose kwargs for setting and modifying index tags

Solution

The usual. The generated bits backing this feature already got created when I generated off the 2025-01 spec.

I added a small amount of logic to handle merging new and existing tags when using configure.

Usage

>>> from pinecone import Pinecone, ServerlessSpec
>>> pc = Pinecone(api_key='key')

# Create index with optional tags dictionary
>>> pc.create_index(
...   name='myindex',
...   dimension=10,
...   metric='cosine',
...   spec=ServerlessSpec(cloud='aws', region='us-west-2'),
...   vector_type='dense',
...   tags={'env': 'testing', 'author': 'jhamon'}
... )
>>> pc.describe_index(name='myindex')
{
    "name": "myindex",
    "metric": "cosine",
    "host": "myindex-dojoi3u.svc.apw5-4e34-81fa.pinecone.io",
    "spec": {
        "serverless": {
            "cloud": "aws",
            "region": "us-west-2"
        }
    },
    "status": {
        "ready": true,
        "state": "Ready"
    },
    "vector_type": "dense",
    "dimension": 10,
    "deletion_protection": "disabled",
    "tags": {
        "author": "jhamon",
        "env": "testing"
    }
}

# Update a tag value. This will be merged with existing tags.
>>> pc.configure_index(
...   name='myindex',
...   tags={'env': 'production'}
... )
>>> pc.describe_index(name='myindex')
{
    "name": "myindex",
    "metric": "cosine",
    "host": "myindex-dojoi3u.svc.apw5-4e34-81fa.pinecone.io",
    "spec": {
        "serverless": {
            "cloud": "aws",
            "region": "us-west-2"
        }
    },
    "status": {
        "ready": true,
        "state": "Ready"
    },
    "vector_type": "dense",
    "dimension": 10,
    "deletion_protection": "disabled",
    "tags": {
        "author": "jhamon",
        "env": "production"
    }
}

# Remove a tag by sending empty string value
>>> pc.configure_index(
...   name='myindex',
...   tags={'author': ''}
... )
>>> pc.describe_index(name='myindex')
{
    "name": "myindex",
    "metric": "cosine",
    "host": "myindex-dojoi3u.svc.apw5-4e34-81fa.pinecone.io",
    "spec": {
        "serverless": {
            "cloud": "aws",
            "region": "us-west-2"
        }
    },
    "status": {
        "ready": true,
        "state": "Ready"
    },
    "vector_type": "dense",
    "dimension": 10,
    "deletion_protection": "disabled",
    "tags": {
        "env": "production"
    }
}

Type of Change

• New feature (non-breaking change which adds functionality)

LGTM

only nit is we may want to include a minimal amount of documentation about needing to use "" to delete / clear a tag

[austin-denoble]

nit: Should the docstring in the interface be updated?

[jhamon]

Yeah, thanks.
