KurrentDB is an event-native database designed for event sourcing and event-driven architectures. It stores events as immutable, ordered records in streams, preserving a complete audit trail and enabling temporal queries. The database uses gRPC for all client-server and inter-node communication, providing efficient binary serialization and bidirectional streaming, and supports atomic multi-stream writes that ensure consistency across multiple streams in a single transaction. The database distinguishes itself with a built-in JavaScript projection engine that transforms, filters, and aggregates
EventStoreDB manages database instances on a Kubernetes cluster using a dedicated operator.
m3 is a distributed time series database designed for high-resolution metrics and high-cardinality data management. It functions as a scalable storage system and a multi-cluster query engine, providing a distributed metrics aggregator capable of downsampling and summarizing data before it is committed to storage. The project distinguishes itself through a coordinated cluster model using etcd for node membership and shard placement. It supports multiple ingestion protocols, including the Prometheus remote write protocol, InfluxDB line protocol, and Graphite Carbon plaintext protocol, and provi
Uses Kubernetes operators and custom resource definitions to automate node placement and operational tasks.
YDB este o bază de date SQL distribuită și un motor analitic conceput pentru scalabilitate orizontală și consistență puternică. Funcționează ca un sistem multi-model care suportă workload-uri tranzacționale și analitice printr-o arhitectură distribuită care oferă tranzacții ACID serializabile. Sistemul se distinge prin compatibilitatea sa largă cu protocoalele, implementând protocolul PostgreSQL pentru driverele SQL standard și protocolul Kafka pentru mesagerie și streaming. Servește, de asemenea, ca o bază de date vectorială, suportând indecși vectoriali și căutări de tip approximate nearest neighbor pentru căutări semantice și embeddings. Platforma gestionează datele folosind un model de stocare hibrid cu formate orientate pe rânduri și pe coloane, utilizând execuția interogărilor vectorizate pentru analize la scară de petabytes. Suprafața sa operațională include streaming de tip change data capture, cozi persistente de tip exactly-once și disponibilitate ridicată multi-zonă. Deployment-ul și gestionarea ciclului de viață sunt susținute printr-un operator Kubernetes și provizionarea de tip infrastructure-as-code.
Employs a Kubernetes operator to automate the installation and lifecycle of storage and dynamic nodes.
The etcd-operator is a custom resource controller designed to automate the deployment, scaling, backup, and recovery of distributed key-value storage clusters on container orchestration platforms. By extending container orchestration APIs with custom resource definitions, the system manages multi-node database instances through declarative configuration files and a continuous controller reconciliation loop that drives cluster provisioning, scaling, and maintenance. The operator provides automated cluster member recovery, detecting unresponsive nodes and executing membership replacements to pr
Deploys custom resource controllers to automate distributed storage instance lifecycles on container platforms.
