Choose the Right Database for IoT

IoT Database Selection Advisor

Adjust requirements to see ranked database recommendations with radar chart comparison

Try

Choose Time-Series Metrics, Time-Range Queries, 10K/s Write Throughput, and Months (1-12), then Check Recommendation.

Observe

The leading candidate's score rises toward 100 as its write and time-range profile matches, while Strong (ACID) can reorder the ranking.

Explain

A 10 ms latency target, relationship model, consistency contract, retention window, and access pattern contribute separate weighted evidence rather than naming one universal database.

Legend. Each coloured polygon is a database candidate; farther from the centre means stronger fit on that workload criterion.

Technical boundaries. Candidate scores are weighted from stated workload requirements and fixed capability profiles. The model does not benchmark engines, size indexes, simulate replication or failure, price a deployment, account for operator skill, or guarantee a database choice.

Goal

Match IoT workload requirements to a database family.

Try

Start with Industrial 50K Sensors, then compare Healthcare Compliance.

Watch

Read the top recommendation reason and the radar chart shape.

Reflect

Which requirement changed the recommendation most: scale, latency, or consistency?

Guided Investigation

1. Start with Industrial 50K Sensors and inspect why a write-optimized option wins.
2. Switch to Healthcare Compliance and notice how joins and ACID change the ranking.
3. Push scale and write throughput higher to see when availability beats SQL richness.

Scenario Focus

Smart Home Hub balances time-series telemetry with modest scale and medium retention.
