About InfluxDB
InfluxDB is a popular open-source time-series database developed by InfluxData, designed to handle high-velocity writes and real-time queries for monitoring, IoT, and analytics use cases. InfluxDB has evolved through multiple versions, with v1 and v2 using a custom storage engine (TSM), while v3 adopts Apache Parquet and Arrow for better performance and compatibility. It features InfluxQL (similar to SQL) and Flux query languages for data analysis. Click here to read the full performance comparison report between GreptimeDB and InfluxDB.
GreptimeDB vs. InfluxDB
| Feature/Aspect | GreptimeDB | InfluxDB |
|---|---|---|
| Data Model | Unified Observability Database | Time-Series Database |
| Value Model | Multi-Value (supports complex data structures) | Multi-Value (tags and fields) |
| Multi-model Support | Metrics, Logs & Traces in one database | Metrics only (requires separate systems for logs/traces) |
| Ingestion Protocols | SQL gRPC InfluxDB Line Protocol Prometheus Remote Storage OpenTelemetry HTTP API | InfluxDB Line Protocol HTTP API Telegraf plugins |
| Query Languages | SQL & PromQL (dual interface) | InfluxQL & Flux (v1/v2) SQL & InfluxQL (v3) |
| Data Retention | Flexible TTL policies with tiered storage | Retention policies with automatic deletion |
| Continuous Aggregation | Built-in SQL aggregation, Pipeline ETL engine & Flow streaming computation | Continuous queries (v1/v2) Tasks and checks (v3) |
| Use Cases | Unified observability, real-time analytics, IoT monitoring, edge computing | IoT monitoring, DevOps metrics, application monitoring |
| Architecture | Cloud-native distributed with compute-storage separation | Single binary (v1/v2) Cloud-native microservices (v3) |
| Storage Format | Apache Parquet (columnar, compressed) | TSM engine (v1/v2) Apache Parquet (v3) |
| Storage Scalability | Object storage integration with unlimited capacity | Local storage (v1/v2) Object storage support (v3) |
| High Availability | Native clustering with automatic failover | Enterprise clustering (v1/v2) Native HA (v3) |
| License | Apache 2.0 | MIT (open source) Commercial (Enterprise) |
| Deployment Options | Single-node, cluster, Kubernetes-native, edge-to-cloud with unified API | Single binary, containerized, cloud-managed |
| Version Compatibility | Consistent API from edge to cloud with unified control plane | Breaking changes between major versions |
| Written Language | Rust (memory safety, performance) | Go (v1/v2) Rust (v3) |
