Most of the open source projects we share with you on InfoQ increase the capabilities of another library or technology. MongoRepository is different in that it intentionally limits the capabilities of the underlying library. We’ll let Rob Janssen why it does this in his own words.
State transitions are an important part of our problem space and should be modelled within our domain, Greg Young states in a recent presentation focusing on basic event sourcing and how CQRS fits in.
MapR recently announced including Apache Drill in its latest release of MapR distribution. Apache Drill is the open source version of Google’s Dremel. Dremel is the infrastructure on which BigQuery is based upon. Drill is offering a low latency SQL-on-Hadoop interface. While this puts it in the same space as several other technologies around Hadoop, Drill has some unique characteristics setting it
A prototype of MySQL 5.7 is shipping with an optional component called the MySQL HTTP Plugin. This plugin allows direct access to MySQL via a REST over HTTP interface, eliminating the need for a middle-tier server or database specific drivers.
Robert C. Martin's advice is to start with shared libraries and a plugin architecture and only when that becomes insufficient consider microservices. Giorgio Sironi argues against this, emphasising how different interactions between microservices are compared to interactions between objects and warns for the cost of retrofitting microservices over an existing code base.
Following on from the Stinger initiative delivered in Apache Hive 0.13, Hortonworks has laid out the Stinger.next roadmap to provide fully ACID transactions, a sub-second query engine, and more complete SQL 2011 analytics support, all driving towards the goal of “enhancing the speed, scale and breadth of SQL support” in Hive.

Vaughn Vernon describes a reactive process manager supervising the process of finding the best loan quotes from banks with a focus on the reactive part, using Actor model for the implementation with examples written in Scala using Akka and C# using his recently published Dotsero toolkit.
The team behind CockroachDB, an open source datastore project, has recently announced its initial alpha version. Inspired by Google’s Spanner project, CockroachDB aims to address the current lack of an open source, scalable, geo-replicated, ACID compliant database.
