Atomix is an event-driven framework for coordinating fault-tolerant distributed systems built on the Raft consensus algorithm. It provides the building blocks that solve many common distributed systems problems including group membership, leader election, distributed concurrency control, partitioning, and replication.
 
Atomix provides a collection of dead simple, asynchronous APIs for sharing mission critical state and solving a variety of common distributed systems problems. It features reliable data consistency guarantees that are maintained even when machine or network failures occur. It clusters are resilient to failure, automatically replacing failed replicas as needed without any data loss. Atomix scales along with the rest of your system, providing high read throughput while maintaining strong write consistency.

Trino is a highly parallel and distributed query engine, that is built from the ground up for efficient, low latency analytics. It is an ANSI SQL compliant query engine, that works with BI tools such as R, Tableau, Power BI, Superset and many others. It helps to natively query data in Hadoop, S3, Cassandra, MySQL, and many others, without the need for complex, slow, and error-prone processes for copying the data. 
 
Access data from multiple systems within a single query. For example, join historic log data stored in an S3 object storage with customer data stored in a MySQL relational database.

Dubbo is a high-performance, java based RPC framework open-sourced by Alibaba. As in many RPC systems, dubbo is based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types. On the server side, the server implements this interface and runs a dubbo server to handle client calls. On the client side, the client has a stub that provides the same methods as the server.

BookKeeper is a replicated log service which can be used to build replicated state machines. A log contains a sequence of events which can be applied to a state machine. BookKeeper guarantees that each replica state machine will see all the same entries, in the same order. It provides back end support to distributed systems, such as messaging systems, coordination systems, filesystems, etc.

Copycat is a fault-tolerant state machine replication framework. Built on the Raft consensus algorithm, it handles replication and persistence and enforces strict ordering of inputs and outputs, allowing developers to focus on single-threaded application logic. Its event-driven model allows for efficient client communication with replicated state machines, from simple key-value stores to wait-free locks and leader elections. You supply the state machine and Copycat takes care of the rest, making it easy to build robust, safe distributed systems.

NoSQLBench is a serious performance testing tool for the NoSQL ecosystem. It brings together features and capabilities that are not found in any other tool. It can run common testing workloads directly from the command line. It can generate virtual data sets of arbitrary size, with deterministic data and statistically shaped values.
 
It is designed for custom workloads that emulate your application, contained in a single file, based on statement templates - no IDE or coding required.
