Top 10 SQL Performance tips & tricks for Java Developers

gvenzl

This slide deck contains some of the most common database performance tips and tricks that developers can use to tune their applications or systems. It also highlights some anti-patterns and shows the impact of these anti-patterns in regard to performance. This slide deck does not aim to be a complete list of all possibilities and techniques to achieve better performance but just highlights some very commonly seen mistakes and how to avoid them.

Acceptance Test-Driven Development: Mastering Agile Testing

TechWell

On agile teams, testers can struggle to keep up with the pace of development if they continue employing a waterfall-based verification process—finding bugs after development. Nate Oster challenges you to question waterfall assumptions and replace this legacy verification testing with acceptance test-driven development (ATDD). With ATDD, you “test first” by writing executable specifications for a new feature before development begins. Learn to switch from “tests as verification” to “tests as specification” and to guide development with acceptance tests written in the language of your business. Get started by joining a team for a simulation and experience how ATDD helps build quality in instead of trying to test defects out. Then progress to increasingly more realistic scenarios and practice the art of specifying intent with plain-language and table-based formats. This isn’t a “tools” session. These are tabletop, paper-based simulations that give you meaningful practice with how executable specifications change the way you think about tests and collaborate as a team. Leave empowered with a kit of exercises to advocate ATDD with your own teams.

stackconf 2023 | How to reduce expenses on monitoring with VictoriaMetrics by...

NETWAYS

Given recent economic changes, cost efficiency has become a top priority for many businesses. This is especially important for monitoring because the nature of telemetry data tends to exponential growth. Many monitoring solutions are now switching their focus to optimize costs. The talk will cover open-source instruments from VictoriaMetrics ecosystem for improving monitoring cost-efficiency. Compression optimization. While ZSTD compression and time series specific techniques like delta-encoding are great, there is still room for improvement. I’ll explain what else can be done to reduce disk footprint for long-term storage. Extra compression on data transferring between metrics collectors and TSDB. I’ll explain how VictoriaMetrics collector reduces the traffic volume by 4 times. Pre-computing for telemetry data on collectors, frequently referred to as edge computing. In VictoriaMetrics it is named as streaming aggregation and allows collectors to pre-compute data, reducing its resolution and cardinality before it is pushed to the database. This is especially important for Prometheus-like systems because streaming aggregation is compatible with Prometheus RemoteWrite protocol and can be used with any system which supports it. Cardinality explorer. Interface, which provides useful insights into data stored by the TSDB. It helps to identify the most expensive metrics or labels and see how they have changed in time. Query tracing. This feature provides details about all the stages of query execution, including time spent on index lookups, disk reads, data transfer, computation, and memory expenses. This is similar to SQL EXPLAIN feature, and helps to improve the performance of read queries. Compute efficiency. VictoriaMetrics components for collecting and storing telemetry data consume fewer resources compared to components from Prometheus ecosystem. It may sound like competition or bragging, but this is a real reason why people migrate from Prometheus to VictoriaMetrics – to cut their infrastructure costs by 2-3 times. All the features listed above are open-source and are available for everyone to use. The talk will be mostly concentrated on typical use cases in monitoring and elegant ways to make things more efficient.

How & When to Feature Flag

Outlyer

Feature flags are a valuable DevOps technique to deliver better, more reliable software faster. Feature flags can be used for both release management (dark launches, canary rollouts, betas) as well as long term control (entitlement management, user segmentation personalization). However, if not managed properly, feature flags can be very destructive technical debt. Feature flags need to be managed properly with visibility and control to both engineering and business users.

Why You Need to Stop Using "The" Staging Server

Outlyer

Old staging methodology is broken for modern development. In fact, the staging server is left over from when we built monolithic applications. Find out why microservice architectures are driving ephemeral testing environments & why every sized dev shop should deliver true continuous deployment. Staging servers slow down development with merge conflicts, slow iteration loops, and manhour intensive processes. To build better software faster containers and infrastructure as code are key in 2017. Dev Ops professionals miss this talk at their own peril.

Ops is dead. long live ops.

Outlyer

Ops is the past! DevOps is the present ! SRE is for giants! NoOps is the future! Fowler even says that a DevOps Engineer is an anti-pattern! So will our job disappear in 10 years? What can we do about it? What is the next set of skills that we need? A startup is often a precursor to larger changes. I'll tell you what we are trying to do at Curve, a Fintech startup where developers build Kubernetes clusters and the SRE team codes microservices.

The service mesh: resilient communication for microservice applications

Outlyer

Modern application architecture is shifting from monolith to microservices: componentized, containerized, and orchestrated with systems like Kubernetes, Mesos, and Docker Swarm. While this environment is resilient to many failures of both hardware and software, applications require more than this to be truly resilient. In this talk, we introduce the notion of a "service mesh": a userspace infrastructure layer designed to manage service-to-service communication in microservice applications, including handling partial failures and unexpected load, while reducing tail latencies and degrading gracefully in the presence of component failure.

Outlyer

Docker (and by extension, microservices based architecture) has expanded our horizons with respect to how the industry builds and supports applications at scale. It’s changed the way we think about our code, what production looks like, and how we live. But in our rush to embrace this exciting new paradigm, are we throwing away the lessons of the past? In this entertaining and somewhat irreverent talk, Corey presents the ”other side” of the containerization craze: how configuration management fits into a world consumed by the Docker Docker Docker madness, how ”containers all the way down” can let you down when you least expect it, and how promising technologies should perhaps be vetted a bit more thoroughly before you try to run critical services on top of them.

Anatomy of a real-life incident -Alex Solomon, CTO and Co-Founder of PagerDuty

Outlyer

Major incidents can be very stressful, frustrating and chaotic experiences, especially if the on-call responders lack the proper process, training and coordination. In this talk, we will walk through a real incident from PagerDuty’s own history, to illustrate what an effective incident response looks like. We will recreate the incident timeline step by step and go over all of the different roles involved, including the incident commander, scribe, customer/business liaison and subject matter experts. We will also cover the process and tooling needed to respond quickly and effectively to major incidents in order to minimize customer and business impact.

On the surface, the tech behind a payments API may look like any other startup’s. You'll probably find some Rails apps, a database, and a bunch of stuff off to the sides to glue it together. GoCardless found it's mostly not the tech that differs, but the approach. Using their high-availability Postgres cluster as a running example, they explore how reliability became so important to them, and dive into the most recent feature they built into the cluster: zero-downtime patch upgrades.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert
