Summary

Pinecone has launched Dedicated Read Nodes (DRN) in Public Preview as of Dec 1, 2025, targeting high-demand vector workloads. This new service provides reserved capacity for applications needing constant high throughput, low latency, and predictable costs, such as billion-vector semantic search, real-time recommendation systems, and mission-critical AI services. Unlike Pinecone's On-Demand service, which is optimized for bursty workloads like RAG, DRN offers hourly per-node pricing for sustained high-QPS scenarios. It features dedicated infrastructure, a warm data path using memory and local SSDs for consistent performance, and scales by adding replicas for throughput and shards for storage capacity. Customer benchmarks demonstrate DRN's capability, including 1.4 billion vectors achieving 5.7k QPS with 26ms P50 latency.

Key takeaway

For AI Architects designing high-scale, latency-sensitive vector search or recommendation systems, Pinecone's Dedicated Read Nodes offer a critical advantage. If your application demands consistent low-latency under heavy load, you should evaluate DRN for its predictable hourly pricing and guaranteed performance. This allows you to provision dedicated resources, ensuring your mission-critical AI services meet strict SLOs without performance degradation or unexpected costs. Consider migrating existing On-Demand indexes to DRN for sustained high-QPS workloads.

Key insights

Pinecone's Dedicated Read Nodes provide reserved, high-performance infrastructure for latency-sensitive, high-throughput vector database workloads.

Principles

• Vector database service selection should align with workload patterns (bursty vs. sustained high-QPS).
• Dedicated infrastructure with warm data paths ensures predictable low-latency and high throughput at scale.
• Scaling throughput and storage capacity can be managed independently via replicas and shards.

Method

Create a DRN index by selecting "Dedicated read nodes" in the Pinecone console, configuring node type (b1/t1), shards (250 GB each), and replicas for desired storage and throughput.

In practice

• Power billion-vector semantic search with strict latency requirements.
• Implement high-QPS recommendation systems and mission-critical AI services.
• Isolate performance for large enterprise or multitenant platforms.
