Vayacondios: Divine into Complex Systems
This presentation given by Flip Kromer and Huston Hoburg on March 24, 2014 at the MongoDB Meetup in Austin.
Vayacondios is a system we're building at Infochimps to gather metrics on highly complex systems and help humans make sense of their operation. You can think of it as a "data goes in, the right thing happens" machine: send in facts from anywhere about anything, and Vayacondios will promptly process and syndicate them to all consumers. Producers don't have to (or get to) worry about the needs of those who will use the data, or the details of transport, storage, filtering or anything else: the data will go where it needs to go. Each consumer, meanwhile, finds that everything they need to know is available to them, on the fly or on demand, without crufty adapters or extraneous dependencies. They don't have to (or get to) worry about the distribution of their sources, the tempo of update, or how the data came to be.
Vayacondios was built for our technical ops team to monitor all the databases and systems they superintend, but it suggests a better way to build database driven applications of any kind. The quiet tyranny of developing against a traditional database has left us with many bad habits: not duplicating data, using models that serve the query engine not the user, assembling application objects from raw parts on every page refresh. Combining streaming data processing systems with distributed datastores like MongoDB let you do your query on the way _in_ to the database -- any number of queries, decoupled, of any complexity or tempo. The resulting approach is simpler, fault-tolerant, and scales in terms of machines and developers. Most importantly, your data models are purely faithful to the needs of your application, uncontaminated by differing opinions of other consumers or by incidentals of the robots that gather and process and store the data.

Data Pipelines with Kafka Connect
In this presentation we describe the design and implementation of Kafka Connect, Kafka’s new tool for scalable, fault-tolerant data import and export. First we’ll discuss some existing tools in the space and why they fall short when applied to data integration at large scale. Next, we will explore Kafka Connect’s design and how it compares to systems with similar goals, discussing key design decisions that trade off between ease of use for connector developers, operational complexity, and reuse of existing connectors. Finally, we’ll discuss how standardizing on Kafka Connect can ultimately lead to simplifying your entire data pipeline, making ETL into your data warehouse and enabling stream processing applications as simple as adding another Kafka connector.
12 Introduction to Rails
Rails is a web application framework written in Ruby that makes programming web applications easier. The key principles of Rails are DRY (Don't Repeat Yourself), convention over configuration, and using RESTful architecture. Rails uses the MVC pattern with models representing data, views representing the user interface, and controllers handling requests and passing data between models and views. Creating a Rails application involves generating the app, setting up the database schema through migrations, and using validations and callbacks to control object state changes.

Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration

Streamlining End-to-End Testing Automation
Streamlining End-to-End Testing Automation with Azure DevOps Build & Release Pipelines
Automating end-to-end (e2e) test for Android and iOS native apps, and web apps, within Azure build and release pipelines, poses several challenges. This session dives into the key challenges and the repeatable solutions implemented across multiple teams at a leading Indian telecom disruptor, renowned for its affordable 4G/5G services, digital platforms, and broadband connectivity.
Challenge #1. Ensuring Test Environment Consistency: Establishing a standardized test execution environment across hundreds of Azure DevOps agents is crucial for achieving dependable testing results. This uniformity must seamlessly span from Build pipelines to various stages of the Release pipeline.
Challenge #2. Coordinated Test Execution Across Environments: Executing distinct subsets of tests using the same automation framework across diverse environments, such as the build pipeline and specific stages of the Release Pipeline, demands flexible and cohesive approaches.
Challenge #3. Testing on Linux-based Azure DevOps Agents: Conducting tests, particularly for web and native apps, on Azure DevOps Linux agents lacking browser or device connectivity presents specific challenges in attaining thorough testing coverage.
This session delves into how these challenges were addressed through:
1. Automate the setup of essential dependencies to ensure a consistent testing environment.
2. Create standardized templates for executing API tests, API workflow tests, and end-to-end tests in the Build pipeline, streamlining the testing process.
3. Implement task groups in Release pipeline stages to facilitate the execution of tests, ensuring consistency and efficiency across deployment phases.
4. Deploy browsers within Docker containers for web application testing, enhancing portability and scalability of testing environments.
5. Leverage diverse device farms dedicated to Android, iOS, and browser testing to cover a wide range of platforms and devices.
6. Integrate AI technology, such as Applitools Visual AI and Ultrafast Grid, to automate test execution and validation, improving accuracy and efficiency.
7. Utilize AI/ML-powered central test automation reporting server through platforms like reportportal.io, providing consolidated and real-time insights into test performance and issues.
These solutions not only facilitate comprehensive testing across platforms but also promote the principles of shift-left testing, enabling early feedback, implementing quality gates, and ensuring repeatability. By adopting these techniques, teams can effectively automate and execute tests, accelerating software delivery while upholding high-quality standards across Android, iOS, and web applications.
