I released spinach 0.2 today.

This release addresses minor issues and allows to use lettuce 3.3.Final. It adds support for more Disque commands and eases creation of a DisqueURI.

lettuce 4.0.Beta2 features ReadFrom Settings. ReadFrom affects how lettuce routes read operations to the members of a Redis Cluster.

By default, lettuce routes its read operations to the master node. Reading from the master returns the most recent version of the data because write operations are issued to the single master node. Reading from masters guarantees strong consistency.

You can reduce latency or improve read throughput by distributing reads to slave members of the Redis cluster for applications that do not require fully up-to-date data. ReadFrom is set per connection, meaning you can use different connections with different ReadFrom settings.

Implementing clean architecture is amazing. A clean architecture fundamentally changes the way you create software and perform changes to existing code. The architectural style, also known as Jacobson architecture or Onion architecture, is based on the business rules. Meaning the application model and use cases. These parts become the explicit core of such an application. The core is agnostic against the database, the web, and frameworks, which are then just plugins to the application.

The Geo-API of the upcoming Redis 3.2 release allows to maintain a set (backed by a Redis sorted set) of Geo points described by WGS84 coordinates. You can add and query set members using the new Geo-API. Use ZREM to remove members from the
until https://github.com/antirez/redis/issues/2674 is resolved.

I released today two betas of lettuce: 3.3.Beta1 and 4.0.Beta1. What is the difference between those versions? Both use netty and a very similar core to serve as Redis driver. The 4.0 branch introduces a Reactive API, stateful connections, improved API and command execution on multiple cluster nodes. 4.0 also introduces a set of breaking changes. The 3.x branch is supported for at least a year, new Redis commands will be supported in both branches. 4.0 is the next generation of lettuce.

CDI is one of the best additions to Java EE of the recent. This opinion is widely shared amongst users and integrators. CDI 1.2, the current version, was released in April, 2014. Now in mid-2015, we face the early draft review of the CDI 2.0 spec. CDI 2.0 will run on Java 8 and higher.

I released the first version of spinach, a scalable Java Disque client based on netty. spinach is built on top of the lettuce client which provides SSL and Unix domain connections in addition to plaintext connections.

Basic usage

DisqueClient client = new DisqueClient("host");
DisqueConnection<String, String> connection = client.connect().sync();
DisqueCommands<String, String> sync = connection.sync();
String jobId = sync.addjob("queue", "body", 1, TimeUnit.MINUTES);

Job<String, String> job = sync.getjob("queue");
connection.ackjob(job.getId());

Features

• Works with Java 6, 7 and 8
• synchronous and asynchronous APIs
• SSL and Unix Domain Socket connections
• Codecs (for UTF8/bit/JSON etc. representation of your data)
