Document Search Pipeline

Compare a typical document search and retrieval workflow.

Pixeltable

import pixeltable as pxt
from pixeltable.functions import openai, huggingface


documents = pxt.create_table('documents', {
    'document': pxt.Document,
    'title': pxt.String,
    'category': pxt.String
})


documents.add_computed_column(
    text_content=pxt.functions.extract_text(documents.document)
)


documents.add_embedding_index(
    'text_content',
    string_embed=huggingface.sentence_transformer.using(
        model_id='all-MiniLM-L6-v2'
    )
)


documents.insert([
    {'document': '/path/to/doc1.pdf', 'title': 'Research Paper', 'category': 'research'},
    {'document': '/path/to/doc2.pdf', 'title': 'Technical Manual', 'category': 'technical'}
])


results = documents.select(
    documents.title,
    documents.category,
    documents.text_content
).search('machine learning algorithms', limit=10)


# Automatic incremental updates — no separate orchestration

Pinecone

import pinecone
from sentence_transformers import SentenceTransformer


pinecone.init(api_key="your-api-key", environment="us-west1-gcp")
index = pinecone.Index("your-index")
model = SentenceTransformer('all-MiniLM-L6-v2')


def process_documents(docs):
    for doc in docs:
        text = extract_text(doc)
        embedding = model.encode(text)
        index.upsert([(doc['id'], embedding, doc)])


def search_docs(query, top_k=10):
    query_embedding = model.encode(query)
    return index.query(
        vector=query_embedding.tolist(),
        top_k=top_k,
        include_metadata=True
    )['matches']


# Separate orchestration needed for updates, versioning, etc.

When to choose which platform

Choose Pixeltable when

  • End-to-End RAG Pipelines

    Document processing, embedding, and retrieval in one system

  • Multimodal Applications

    Beyond text embeddings — images, video, audio

  • Automatic Sync

    Embeddings stay in sync when source data changes

  • Reduced Tool Sprawl

    Replace vector DB + ETL + orchestrator with one platform

Choose Pinecone when

  • Pure Vector Search at Scale

    Existing pipeline, need only a managed vector index

  • Maximum Query Performance

    Dedicated ANN infrastructure for billion-scale indexes

  • Simple Upsert/Query API

    Embeddings already computed elsewhere

  • Multi-Region Serving

    Managed global vector index with low latency

Making the right choice

  • From Pinecone to Pixeltable

    • Eliminate separate ETL and orchestration for embedding pipelines
    • Need automatic incremental updates when documents change
    • Require data lineage linking embeddings to source media
    • Building multimodal applications beyond text-only vectors

  • Complementary Usage

    • Pixeltable for data processing and workflow orchestration
    • Export processed embeddings to Pinecone for specialized serving when needed
    • Pixeltable covers 90% of vector search use cases without external DB
