GreptimeDB is a distributed, open-source time-series database built for unified observability. It stores and queries metrics, logs, and traces together in a single columnar engine, supporting both SQL and PromQL for analysis. The database is designed as a Kubernetes-native operator with a decoupled compute and storage architecture, enabling horizontal scaling and multi-region deployment. What distinguishes GreptimeDB is its role as a multi-protocol ingestion gateway, accepting data through OpenTelemetry, Prometheus Remote Write, InfluxDB, Loki, Elasticsearch, Kafka, and MQTT protocols without
CloudNativePG is a Kubernetes operator designed for the administration, lifecycle management, and high availability of PostgreSQL database clusters. It functions as a declarative orchestrator that manages database instances through custom resources and manifests. The project distinguishes itself by automating complex operational tasks, including primary election and failover management via streaming physical replication. It provides specialized tools for database version migrations, supporting both offline in-place upgrades and online migrations through logical replication. The operator cove
Pigsty is a comprehensive database infrastructure orchestration platform designed to automate the full lifecycle of high-availability PostgreSQL clusters. It functions as an infrastructure-as-code framework that manages cluster coordination, node provisioning, and service discovery through idempotent playbooks. By integrating distributed consensus mechanisms, the platform ensures automated failover and consistent state enforcement across diverse environments, including bare metal and virtualized infrastructure. The platform distinguishes itself through a robust suite of operational capabiliti
TiDB is a horizontally scalable, distributed SQL database designed to provide consistent transactional storage and high-performance analytical processing within a single unified architecture. It utilizes a decoupled compute-storage design and a distributed key-value storage layer to ensure horizontal scalability and efficient range-based queries. By employing a consensus-based replication algorithm, the system maintains high availability and automatic failover across multiple nodes and geographical regions. The platform distinguishes itself through its hybrid transactional and analytical proc
The project is a Kubernetes operator that automates the deployment, configuration, and management of ClickHouse database clusters using native custom resources and declarative manifests. It functions as a distributed database controller and stateful workload manager, handling infrastructure provisioning and scaling routines across containerized environments.
