TiKV is a cloud-native distributed transactional key-value store and storage engine. It provides a distributed database designed for horizontal scalability and strong consistency across a cluster of physical nodes. The system uses a Raft-based consensus mechanism to maintain data availability and state synchronization. It ensures ACID compliance for distributed transactions through a two-phase commit workflow and manages data distribution via multi-Raft sharding. The engine handles massive datasets using automated range splitting and cluster load balancing to distribute data across different

Cassandra is a distributed NoSQL database and wide-column store designed for high availability and linear scalability. It functions as a fault-tolerant distributed system that utilizes an LSM-tree storage engine to optimize write throughput and manage massive datasets. The system is a CQL-compliant database, using a structured query language to manage and retrieve tabular data stored across multiple nodes. It organizes information into rows and columns based on a flexible schema and primary keys. The project provides capabilities for horizontal database scaling, distributed data partitioning

Hazelcast is a distributed data platform that combines an in-memory data grid with a stream processing engine to support real-time analytics and event-driven applications. It functions as a partitioned, distributed key-value store that replicates data across cluster nodes to provide low-latency access and high availability. The platform also serves as a distributed SQL query engine, allowing users to execute standard SQL statements against both in-memory datasets and external data sources. What distinguishes Hazelcast is its use of a distributed consensus subsystem to maintain strongly consis

Kanidm is a centralized identity management server designed to handle authentication, authorization, and directory services across distributed infrastructure. It provides a comprehensive framework for managing human and service accounts, utilizing a schema-driven database to store identity records, group memberships, and system attributes. The platform supports a wide range of authentication methods, including passkeys, passwords, and standard protocols like OAuth2, OIDC, LDAP, and RADIUS. The system distinguishes itself through a granular access control engine that enforces security policies

Zeebe ist eine Cloud-native Workflow-Engine und eine verteilte Zustandsmaschine, die für die Orchestrierung von Geschäftsprozessen unter Verwendung von BPMN- und DMN-Standards konzipiert wurde. Sie arbeitet als hochperformante gRPC-Workflow-Runtime, die komplexe Geschäftsprozesse durch eine partitionierte Event-Streaming-Architektur ausführt. Das System fungiert zudem als Orchestrator für Large-Language-Model-Agenten und koordiniert KI-Reasoning und Tool-Nutzung innerhalb deterministischer Geschäftsprozesse. Die Engine zeichnet sich durch ihr Peer-to-Peer-Broker-Networking und ein konsensbasiertes Datenreplikationsmodell aus, das hohe Verfügbarkeit und Fehlertoleranz sicherstellt.
