## Standing by category

| Category | Share | Rank | Negative rate | Labels |

## What the models said for it

- "Use PostgreSQL + JSONB if you're early-stage and want maximum flexibility with minimal cost." (GPT-5.4 mini, NoSQL)
- "The Best "All-in-One" Alternative: PostgreSQL (with JSONB)" (Gemini 3.5 Flash, NoSQL)
- "TL;DR: Default to Postgres. Reach for NoSQL only when you can state the specific access pattern or scale wall that forces it." (Muse Glimmer 30B, NoSQL)
- "an existing PostgreSQL or analytics platform may be sufficient if the workload is moderate and relational joins matter" (Perplexity Sonar, Time series DBs)

## And against it

- "Avoid using relational databases for high-scale time series workloads" (Mistral Small, Time series DBs)
- "Traditional relational databases (like MySQL or standard Postgres) often struggle with the high velocity, append-only nature" (Qwen 3.7 Flash, Time series DBs)
- "Plain PostgreSQL or MySQL for very large time-series workloads... Use them cautiously" (Perplexity Sonar, Time series DBs)
- "They work but hit walls on high ingest rates, cardinality explosions, index bloat" (Grok 4.20, Time series DBs)
