What is Kubegres?
It is a Kubernetes operator allowing to deploy a cluster of PostgreSql instances with data replication enabled out-of-the box. It brings simplicity when using PostgreSql considering how complex managing stateful-set's life-cycle and data replication could be with Kubernetes.
Kubegres is a tool in the Container Registry category of a tech stack.
Key Features
It creates a cluster of PostgreSql servers with Streaming Replication enabled: it creates a Primary PostgreSql pod and a number of Replica PostgreSql pods and replicates primary's database in real-time to Replica podsIt manages failover: if a Primary PostgreSql crashes, it automatically promotes a Replica PostgreSql as a PrimaryIt has a data backup option allowing to dump PostgreSql data regularly in a given volumeIt provides a very simple YAML with properties specialised for PostgreSqlIt is resilient, has over 55 automatized tests cases and has been running in productionIt works with the PostgreSql containers created by the Docker Official Images team. Kubegres uses the standard PostgreSql libraries to manage replication and failover and it does not require a custom Docker image with a set of third party librariesIt is portable because compatible with any Docker images which derive from the PostgreSql containers

Slick
It is a modern database query and access library for Scala. It allows you to work with stored data almost as if you were using Scala collections while at the same time giving you full control over when a database access happens and which data is transferred.
