We are excited to introduce a Python SDK for PostgresML that streamlines the development of scalable vector search applications on PostgreSQL databases. Traditionally, building a vector search application requires spinning up an application database, connecting to external OpenAI or HuggingFace REST API services for generating embeddings, and integrating with vector databases like Pinecone for indexing and search. This approach increases infrastructure footprint, maintenance efforts, and query latency.
With the PostgresML Python SDK, developers now have a unified solution. They can effortlessly manage a single application database where they can handle: document management, embedding generation, indexing, and searching. This eliminates the need for multiple infrastructure components, simplifies maintenance, and reduces query latencies. The SDK offers a comprehensive set of tools for managing database tables related to documents, text chunks, text splitters, LLM models, and embeddings, enabling seamless integration of advanced search functionalities.

The Python SDK automates the management of various database tables, eliminating the complexity of setting up and maintaining the data structure required for vector search applications. With this automated system, you can focus on building robust search functionalities while the SDK handles the underlying database management.
Leveraging the Python SDK, you gain access to a vast collection of open source models. These models have been trained on extensive datasets and capture the semantic meaning of text. With just a few lines of code, you can generate embeddings using these models, enabling powerful analysis and search capabilities in your application.
The Python SDK seamlessly integrates with PgVector, a PostgreSQL extension designed for efficient vector-based indexing and querying. By leveraging the power of PgVector, you can perform advanced searches, rank results by relevance, and retrieve accurate and meaningful information from your database. The SDK ensures that your vector search application scales effortlessly to handle increasing amounts of data.
The Python SDK simplifies the development of vector search applications by abstracting away the complexities of database management and indexing. Here's an overview of how it works:
The SDK simplifies the process of upserting documents and generating text chunks by offering a user-friendly interface. It allows you to effortlessly add and configure various text splitters to generate text chunks of different sizes, overlaps, and file formats, such as Python and Markdown.
With the SDK, you can seamlessly incorporate a wide range of open source models from HuggingFace into your application. These models capture the semantic meaning of text and enable powerful analysis and search capabilities. Generating high-quality embeddings from these models is a breeze with the Python SDK.
The Python SDK utilizes the PgVector extension to efficiently index the embeddings generated by the open source models. This indexing process optimizes search performance and allows for fast and accurate retrieval of relevant results, even with large volumes of data.
Once the embeddings are indexed, the SDK provides intuitive methods for executing vector-based searches on the documents and text chunks stored in the PostgreSQL database. You can easily execute queries and retrieve search results with precise and relevant information.
The Python SDK's embedding capabilities find applications in various scenarios, including:
By comparing embeddings of query strings and documents, you can retrieve search results ranked by their relevance or similarity to the query. This allows users to find the most relevant information quickly and effectively.
Utilizing embeddings, you can group text strings based on their similarity. By measuring the similarity between embeddings, you can identify clusters or groups of text strings that share common characteristics, providing valuable insights for data analysis.
Embeddings play a crucial role in recommendation systems. By identifying items with related text strings based on their embeddings, you can deliver personalized recommendations to users, enhancing user experience and engagement.
Anomaly detection involves identifying outliers or anomalies in data. By quantifying the similarity between text strings using embeddings, you can identify anomalies that have little relatedness to the rest of the data, aiding in anomaly detection tasks.
Embeddings are valuable in classification tasks, where text strings are classified based on their most similar label. By comparing the embeddings of text strings and labels, you can accurately classify new text strings into predefined categories.
