...Apart from its blazing speed, ClickHouse is highly reliable and fault tolerant. It supports multi-master asynchronous replication with the option of being deployed across multiple datacenters. With all nodes equal, there is no single point of failure. Downtime of a single node or even the whole datacenter won't affect the system's availability. ClickHouse also has exceptional hardware efficiency and a host of other features, including a feature-rich SQL database, vectorized query execution, real-time query processing and data ingestion, and more.

...YugabyteDB reuses PostgreSQL’s query layer and supports all advanced features. Scale-out and in with zero impact. Proven in production to scale beyond 300K TPS, over 100TB of data, and thousands of concurrent connections. Achieve continuous availability during infrastructure failures and on maintenance tasks such as software upgrades and distributed backups. Use powerful replication and data geo-partitioning capabilities to achieve the latency, resilience, and compliance your applications need. Deploy YugabyteDB in public, private, and hybrid cloud environments, on VMs, containers, or bare metal. ...

Manticore Search is an easy to use open source fast database for search. Modern MPP architecture and smart query parallelization capabilities allow to fully utilize all your CPU cores to lower response time as much as possible, when needed. Powerful and fast full-text searching which works fine for small and big datasets. Columnar storage support via the Manticore Columnar Library for bigger datasets (much bigger than can fit in RAM). SQL-first: Manticore's native syntax is SQL. It speaks...

Object-Relational Main-Memory Embedded Database system tightly integrated with C++ language. Use OS virtual mapping mechanism to access data. Provides subset of SQL language with OO extensions. Support of transactions, fault tolerance, replication.

...Most redis commands are supported, and a few new commands. Ardb commands VS Redis Commands. Multi storage engines supported. RocksDB, LevelDB, LMDB, WiredTiger, PerconaFT, ForestDB. Multi data structure types supported, String, List, Set, Sorted Set, Hash, Bitmap(String), HyperLogLog(String), 2D Spatial Index(Sorted Set), Stream. Replication compatible with Redis 2.6/2.8. Ardb instance work as slave of Redis 2.6/2.8+ instance. Arab instance work as master of Redis 2.6/2.8+ instance. Ardb instance work as slave of Ardb instance. ...

DBRE - is a system for asynchronous point-in-time databases replication. In addition, it can be used for a single transfusion of data between the DBMS

A high speed data store to store the system state of network and telecommunication switches.

VDDBMS is a middleware for managing data sources (DBMS) from different vendors to form a virtual DDBMS. It supports fragmentation and replication. The core engine is written in C++. Binding for scripting language is available as well as network access.
