Voldemort does not try to satisfy arbitrary relations and the ACID properties, but rather is a big, distributed, persistent hash table. [2] A 2012 study comparing systems for storing application performance management data reported that Voldemort, Apache Cassandra, and HBase all offered linear scalability in most cases, with Voldemort having the lowest latency and Cassandra having the highest ...
Distributed SQL databases have the following general characteristics: synchronous replication; strong transactional consistency across at least availability zones (i.e. ACID compliance) [6] relational database front end structure – meaning data represented as tables with rows and columns similar to any other RDBMS; automatically sharded data ...
The data can be stored both locally (on a personal computer) and on a shared storage (e.g., a lab database). UGENE integrates dozens of well-known biological tools, algorithms, and original tools in the context of genomics , evolutionary biology , virology , and other branches of life science.
Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed ...
Apache Iceberg is a high performance open-source format for large analytic tables.Iceberg enables the use of SQL tables for big data while making it possible for engines like Spark, Trino, Flink, Presto, Hive, Impala, StarRocks, Doris, and Pig to safely work with the same tables, at the same time.

Elliptics is a distributed key–value data storage with open source code. By default it is a classic distributed hash table (DHT) with multiple replicas put in different groups (distributed hashes). Elliptics was created to meet requirements of multi-datacenter and physically distributed storage locations when storing huge amount of medium and ...
