Designing the Perfect Elasticsearch Cluster: the (almost) Definitive Guide
"Cluster design is an overlooked part of running Elasticsearch. Offical documentation and blog posts focus on the magic of deploying a cluster in a giffy, while the first problem people face when deploying in production is memory management issues, aka garbage collection madness. This guide answers most questions I was asked, and summarises everything you should know about designing the perfect Elasticsearch cluster."

GitHub - sorintlab/stolon: PostgreSQL cloud native High Availability and more.
stolon is a cloud native PostgreSQL manager for PostgreSQL high availability. It's cloud native because it'll let you keep an high available PostgreSQL inside your containers (kubernetes integration) but also on every other kind of infrastructure (cloud IaaS, old style infrastructures etc...)

Accord: A high-performance coordination service for write-intensive workloads
"Accord is a high-performance coordination service like Apache ZooKeeper that uses Corosync Cluster Engine as a total-order messaging infrastructure. It features:

Accord is a distributed, transactional, and fully-replicated (No SPoF) Key-Value Store with strong consistency.
Accord can be scale-out up to tens of nodes.
Accord servers can handle tens of thousands of clients.
Any clients can issue I/O requests, and any servers can accept and process I/O requests.
The changes for a write request from a client can be notified to the other clients.
Accord detects events of client's joining/leaving, and notifies joined/left client information to the other clients.
The difference between Accord and ZooKeeper is:

Accord focuses on write-intensive workloads unlike ZooKeeper. ZooKeeper forwards all write requests to a master server. It can be bottleneck in write-intensive workloads. The below benchmark demonstrates that the write-operation throughput of Accord is much higher than one of ZooKeeper (up to 18 times better throughput at persistent mode, and up to 20 times better throughput at in-memory mode).
More flexible transactions are supported. Not only write, del operations, cmp, copy, but also read operations are supported in transaction operations.
In-memory mode and persistent mode supported.
Message size is unbounded, and partial update is supported."

Spark | Lightning-Fast Cluster Computing
"Spark is an open source cluster computing system that aims to make data analytics fast — both fast to run and fast to write.

To run programs faster, Spark provides primitives for in-memory cluster computing: your job can load data into memory and query it repeatedly much quicker than with disk-based systems like Hadoop MapReduce.

To make programming faster, Spark provides clean, concise APIs in Scala, Java and Python. You can also use Spark interactively from the Scala and Python shells to rapidly query big datasets."
