Patroni is a high availability manager and cluster orchestrator for PostgreSQL. It functions as an automatic failover controller and replication manager that ensures continuous database availability by automating leader election and promoting standby nodes during failures. The system maintains a consistent cluster state by acting as a distributed consensus coordinator. It synchronizes configuration and manages leader elections through integration with distributed configuration stores such as etcd, ZooKeeper, or Consul. Its broader capabilities include managing both synchronous and asynchrono

Disque is a distributed message broker that manages asynchronous communication between services through in-memory job queues. It operates as a cluster-aware job scheduler, providing at-least-once delivery guarantees with acknowledgment and retry mechanisms, and supports blocking queue consumers that efficiently wait for jobs to become available. The broker implements a job state machine that tracks each job through its lifecycle from queued to acknowledged, with configurable retry limits and time-to-live expiration to prevent unbounded queue growth. Jobs can be enqueued with delivery guarante

Kraken is a distributed blob store and peer-to-peer Docker registry designed for the high-throughput distribution of container images. It functions as a decentralized content delivery network that shares image layers across a network of nodes to prevent bottlenecks at a central registry. The system utilizes peer-to-peer blob distribution and distributed content addressing to maintain download speeds across large clusters. It implements asynchronous rule-based replication to synchronize image data between disparate geographical clusters. The project covers pluggable external blob storage inte

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

FalkorDB is a high-performance graph database management system and vector graph database. It serves as a knowledge graph construction tool and a GraphRAG knowledge store, integrating structured property graphs with vector search to provide grounded context for large language models. The engine is designed as a multi-tenant graph engine, capable of hosting thousands of isolated datasets within a single instance. The system distinguishes itself by using linear algebra for query execution, treating relationship tensors as matrix multiplications to achieve low-latency multi-hop traversals. It ut
