DataStax announced a new integration with LangChain, the popular orchestration framework for developing applications with large language models (LLMs). The integration makes it easy to add Astra DB – the real-time database for developers building production Gen AI applications – or Apache Cassandra, as a new vector source in the LangChain framework. 

As companies implement retrieval augmented generation (RAG) – the process of providing context from outside data sources to deliver more accurate LLM query responses – into their generative AI applications, they require a vector store that provides real-time updates with zero latency on critical production workloads.

Generative AI applications built with RAG stacks require a vector-enabled database and an orchestration framework like LangChain to provide memory or context to LLMs for accurate and relevant answers. Developers use LangChain as an AI-first toolkit to connect their application to different data sources.

The integration lets developers leverage the Astra DB vector database for their LLM, AI assistant, and real-time generative AI projects through the LangChain plugin architecture for vector stores. Together, Astra DB and LangChain help developers to take advantage of framework features like vector similarity search, semantic caching, term-based search, LLM-response caching, and data injection from Astra DB (or Cassandra) into prompt templates.

dbt Labs has announced the next generation of the dbt Semantic Layer following its acquisition of Transform in February 2023. The dbt Semantic Layer enables organizations to centrally define business metrics in dbt Cloud and then query them from any integrated analytics tool. This allows organizations to ensure that critical definitions such as “revenue,” “customer count,” or “churn rate” are consistent in every data application.

dbt Labs is also shipping a new integration with Tableau for the dbt Semantic Layer. With this integration organizations that rely on Tableau’s analytics platform can benefit from business-critical metrics that are consistent, reliable, and reading from a single, verified source of truth. The Semantic Layer also integrates with Google Sheets, Hex, Klipfolio, Lightdash, Mode, and Push.ai. New features:

• Dynamic join support: Join any number of tables together to produce metrics on top of an existing database.
• Optimized query plans and SQL generation: Generates joins, filters and aggregations as an analyst would, with legible and performant SQL.
• Complex metric types: Enables new aggregations and more flexible metric definitions, empowering users to define more metrics critical to measuring their business.
• Expanded data platform support: Supports BigQuery, Databricks, Redshift, and Snowflake, including performance optimizations for each.
