What is Vector Database Selection?
Choosing vector database for RAG and semantic search from Pinecone, Weaviate, Qdrant, pgvector, Milvus based on scale, performance, features, and costs. Critical infrastructure for LLM applications with embedding search.
This glossary term is currently being developed. Detailed content covering implementation guidance, best practices, vendor selection, and business case development will be added soon. For immediate assistance, please contact Pertama Partners for advisory services.
Understanding this concept is critical for successful AI implementation and business value realization. Proper evaluation and execution drive competitive advantage while managing risks and costs.
- Scale: million to billion+ vector storage requirements
- Performance: query latency and throughput needs
- Features: filtering, hybrid search, multi-tenancy
- Deployment: managed cloud vs self-hosted
- Pricing: storage + query costs, often $100-1000s/month
Common Questions
How do we get started?
Begin with use case identification, stakeholder alignment, pilot program scoping, and vendor evaluation. Expert guidance accelerates time-to-value.
What are typical costs and ROI?
Costs vary by scope, complexity, and deployment model. ROI depends on use case, with automation and analytics often showing 6-18 month payback.
More Questions
Key risks: unclear requirements, data quality issues, change management, integration complexity, skills gaps. Mitigation through phased approach and expert support.
Prioritise query latency at your expected scale (measure at 10x projected volume), filtering capabilities for metadata-based narrowing before vector search, operational maturity including backup and monitoring tools, and total cost including storage and compute at full dataset size. Pinecone offers the simplest managed experience, Weaviate provides strong hybrid search, and pgvector minimises infrastructure complexity for teams already running PostgreSQL. Avoid over-engineering: start simple and migrate if performance demands it.
Managed services like Pinecone cost USD 70-700 monthly for 1-10 million vectors depending on performance tier. Self-hosted options like Qdrant, Milvus, or Weaviate run on infrastructure costing USD 200-2,000 monthly depending on dataset size and query throughput requirements. Pgvector on existing PostgreSQL instances adds near-zero marginal cost for small-to-medium deployments under 5 million vectors, making it the most economical starting point for teams evaluating vector search viability.

Structured plan for deploying AI across organization including current state assessment, use case prioritization, technology selection, pilot execution, scaling strategy, and change management. Typical 6-18 month timeline from strategy to production deployment.
Controlled initial deployment of AI solution to validate technology, measure business impact, and de-risk full-scale implementation. Typical 8-16 week duration with defined scope, metrics, and go/no-go decision criteria before enterprise rollout.
Evaluation framework measuring organization's AI readiness across strategy, data, technology, people, processes, and governance. Benchmarks current state against industry and identifies gaps to prioritize investment and capability building.
Shortage of talent with AI/ML expertise including data scientists, ML engineers, AI product managers, and business translators. Addressed through hiring, training, partnerships with vendors/consultants, and low-code/no-code platforms reducing technical barriers.
Organizational principles and guidelines for responsible AI use addressing fairness, transparency, privacy, accountability, and human oversight. Operationalized through ethics review boards, impact assessments, and built-in technical controls.
