Optimizing queries in Splunk’s Search Processing Language is similar to optimizing queries in SQL. The two core tenants are the same: Change the physics and reduce the amount of work done. Added to that are two precepts that apply to any distributed query.
When working with Hadoop, with or without Hunk, there are a number of ways you can accidentally kill performance. While some of the fixes require more hardware, sometimes the problems can be solved simply by changing the way you name your files.
This post talks about five innovative kanban boards.
The volatility in the market requires that organizations become able to adapt to changing demand as fast as possible while gaining the highest value. To implement agile managers need to team up to remove impediments in the organization says Ahmet Akdag. An agility transformation is about learning to try, fail and learn.
Mike Orzen will talk about using core work systems to drive transformational behavior at the Lean IT Summit 2015. An interview on the benefits that organizations aim for with lean IT, why adopting and reinforcing new behaviors is essential to create sustained change, core work systems and work processes for IT organizations, and common missteps in lean IT transformations and how to prevent them.
RebelLabs published their Developer Productivity Report, the result of a survey started in March 2015, where they polled the Java development community on Java performance and performance testing methods. To see how these numbers line up with a real world experience, InfoQ spoke with Kirk Pepperdine, CTO at JClarity and well-known performance expert.
QASymphony has released qMap, a visual mapping solution for agile testers of cloud, mobile, big data and IoT apps. InfoQ did an interview with Kyle Cochran about why qMap was developed, how testers can use qMap to get insight into their testing results and manage testing and can use information from qMap improve the quality of their product, and how QMap can be deployed within agile and DevOps.
A database query times out and you don’t know why. The estimated query plan is revealing the problem, so you remove the timeout entirely. An hour later it is still running and you are no closer to getting the actual execution plan. If only there was a way to find out what is actually happening inside the server. With Live Query Statistics in SQL Server 2016 you can now answer that question.
Tomas Rybing shared the concept of the customized kanban board named ‘Arrow’. The Arrow is based on the priority pyramids approach. Arrow is a visualization of the backlog combined with the kanban board that visualizes the work process.
At the recent devopsdays Amsterdam 2015, Patrick Roelke contended that monitoring still has lots of issues. Roelke believes that data science can help by eliminating static thresholds and coalescing information from various data sources into a single metric. The talk included a quick overview of monitoring tools that leverage data science: Kale, Bosun and AnomalyDetection.
David Mytton, CEO at Server Density, shared with the devopsdays Amsterdam 2015 crowd how they handle incidents and outages.

At GlueCon 2015, Adrian Cockcroft presented a list of rules for monitoring microservice and container-based applications. In addition to these guidelines, Cockcroft also highlighted a series of challenges for monitoring cloud-native container-based systems, and introduced his ‘Spigo/simianviz’ microservice simulation and visualisation tool.
New Relic has released a set of new features to its Software Analytics Platform. Service Maps is a real time visual map focused on services.
