Improved Price-to-Performance with Support for ARM Architecture

Crunchy Postgres for Kubernetes 5.4 introduces support for ARM, a game-changing advancement that brings significant cost savings and improved price-to-performance ratio for businesses. By harnessing the power of ARM architecture, Crunchy Postgres for Kubernetes now enables organizations to leverage cost-efficient hardware while delivering exceptional performance. This capability opens doors to a wide range of use cases, from cloud and hyperscale deployments to edge computing scenarios.

Support for Native Vector Search

Crunchy Postgres for Kubernetes 5.4 includes the pgvector extension. This allows Postgres to be extended to natively store, index, and query OpenAI embeddings, empowering LLM hydration and results directly in Postgres running in Kubernetes.

Enhanced Performance and Operational Safeguards

Crunchy Postgres for Kubernetes 5.4 introduces a collection of improvements designed to improve performance and operational stability, including:

  • Comprehensive Support for Huge Pages. Leveraging this Linux kernel feature, Crunchy Postgres optimizes memory efficiency when dealing with large memory workloads. By leveraging huge pages, enterprises can now witness a notable boost in Postgres performance while safeguarding critical Postgres background processes from the Linux Out Of Memory (OOM) killer. This added layer of protection ensures uninterrupted operations and reinforces the stability of your PostgreSQL deployments.
  • Native support for Tablespaces. Native Postgres tablespace management grants administrators greater control and flexibility in managing their database storage. With the ability to define tablespaces, businesses can now efficiently organize and allocate storage resources, optimizing data placement and streamlining database operations. This functionality empowers enterprises to tailor their PostgreSQL environments to their unique requirements while maintaining the utmost performance and data integrity.
