GreptimeDB
GreptimeDB is an open-source observability database for storing and querying metrics, logs and traces through a columnar engine and shared SQL layer.
What GreptimeDB is
GreptimeDB is an open-source observability database for storing and querying metrics, logs and traces through a columnar engine and shared SQL layer. It targets append-heavy, time-indexed workloads such as observability and IoT data rather than general-purpose transactional database use. Users can query signal tables with SQL and metrics with PromQL. It accepts connections through MySQL, PostgreSQL, gRPC, Prometheus, OpenTelemetry and InfluxDB line protocol endpoints. Documented integrations include Prometheus, Grafana, Kafka, Apache Flink, Apache Spark, Telegraf, EMQX and Fluent Bit. GreptimeDB can run standalone or as a horizontally scalable cluster; downloads include Kubernetes Helm charts, Docker images and binaries for macOS, Linux, Windows and Android ARM64. Its feature list includes object storage support and indexes for high-cardinality data. Open-source security options include username/password authentication, user-level read/write access control and TLS/SSL connections. Enterprise adds LDAP, fine-grained RBAC, audit logging and encryption at rest, alongside technical support and SLA-backed response times.
