TECHNOLOGY PROFILE · TECH-0102
Haystack
Composable pipelines for search and language-model applications.
Reference link only — not reviewed this edition. This profile preserves the prepared catalog’s original descriptions. Advantages depend on the workload; comparisons are editorial, not benchmark results.
Where it has an edge
Explicit retrieval and generation components suit testable search pipelines rather than an opaque agent loop.
Best-fit problems
Production-oriented RAG and document question answering.
Tradeoffs & cautions
Component compatibility and deployment still require engineering.
What to test before choosing
Test interrupted/resumed runs, tool authorization, retrieval quality, cost caps and failure recovery.
Runtime & hardware
Usually application server
Access & licensing
Open-source cores; hosted additions may cost
Execution
Local / self-hosted
Lifecycle
Not independently audited
Comparison basis
Editorial problem-fit judgement; no head-to-head benchmark performed
