## What it is
GridDB is an open-source, high-performance distributed database optimized for time-series IoT and big data workloads, offering both NoSQL and SQL interfaces. It is written in C++ with a Java client and JDBC driver, featuring in-memory orientation, scale-out clustering, and petabyte-scale data management.

## Use cases
- store and query high-frequency sensor data from IoT devices
- ingest massive time-series data streams in real time
- run SQL analytics over NoSQL-collected telemetry
- build petabyte-scale big data pipelines with millisecond queries
- set up a highly available clustered database for cyber-physical systems
- replace a general-purpose database for time-series-heavy workloads

## When to choose
- your workload is dominated by time-series IoT or sensor data at high write frequency
- you need both NoSQL ingestion and SQL querying in one database
- you require horizontal scale-out clustering with high availability
- you need petabyte-scale storage with in-memory performance characteristics

## When to avoid
- you need a simple embedded or single-node database for a small app
- your primary platform is Windows or macOS (Linux x64 is the supported target)
- you need rich ecosystem tooling and ORMs comparable to PostgreSQL or MySQL
- AGPL-3.0 licensing is incompatible with your project

## Facets
- artifact type: service
