GreptimeDB
What GreptimeDB is
GreptimeDB is an open-source observability database for storing and querying metrics, logs, and traces. Its columnar engine and shared SQL layer target append-heavy, time-indexed workloads such as observability and IoT, rather than general-purpose transactional databases. It supports SQL across signal tables and PromQL for metrics, with ingestion options including OpenTelemetry, Prometheus Remote Write, Loki Push API, Elasticsearch Bulk API, InfluxDB Line Protocol, MySQL, PostgreSQL, gRPC, and HTTP. Documented integrations include Prometheus, Grafana, Kafka, Apache Flink, Apache Spark, Telegraf, EMQX, and Fluent Bit. It 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. Listed features include object storage support and several index types for high-cardinality data. Open-source security includes basic authentication, user-level read/write access control, and TLS/SSL. Enterprise adds options such as LDAP, fine-grained RBAC, audit logging, and encryption at rest, along with support and SLA-backed response times. The fully managed Enterprise plan starts at $290/month; the open-source edition has community support through Slack and GitHub.
