// Differentiators
Why teams pick InfluxDB.
When evaluating self-hosted options for this category, here are the dimensions on which InfluxDB consistently lands above the alternatives.
- ✓MIT (OSS) — fully open for community use
- ✓Industry standard — most documentation, integration, tooling
- ✓Flux query language — powerful + composable
- ✓Retention policies built-in — auto-downsample + expire data
- ✓Grafana native — first-class data source
- ✓High write throughput — optimized for sensor / metric ingestion

// Tips & operations
Run it properly.
Operational guidance from running this in production — what to lock down, what surprises people.
// PERFORMANCE
InfluxDB 2.x vs 3.x
2.x is stable, 3.x in transition; we ship 2.7 (current stable)
// SECURITY
Retention discipline
default bucket has 30-day retention; tune per use case
// OPERATIONS
Cardinality kills
high-cardinality tags (user IDs, trace IDs) cause issues
// RELIABILITY
Backup snapshot
influx backup for periodic disaster recovery
// DEPLOYMENT
Token security
admin token gives full access; create scoped tokens per consumer
// SCALING
