This document discusses various techniques for distributed coordination including event ordering, mutual exclusion, atomicity, concurrency control, deadlock handling, election algorithms, and reaching agreement. It provides details on implementing happened-before relations for event ordering, centralized and distributed approaches for mutual exclusion, using two-phase commit for atomicity, locking protocols and timestamp ordering for concurrency control, deadlock prevention and detection methods, and election algorithms for determining where to restart a coordinator process.
Trafodion brings a completely distributed scalable transaction management implementation integrated into HBase. It does not suffer from the scale and performance limitations of other transaction managers on HBase.
This presentation reviews the elegant architecture and how this architecture is leveraged to provide full ACID SQL transactional capabilities across multiple rows, tables, statements, and region servers. It discusses the life of a transaction from BEGIN WORK, to updates, to ABORT WORK, to COMMIT WORK, and then discusses recovery and high availability capabilities provided. An accompanying white paper goes into depth explaining this animated presentation in more detail.
Given the increasing interest for transaction managers on Hadoop, or to provide transactional capabilities for NoSQL users when needed, the Trafodion community can certainly open up this Distributed Transaction Management support to be leveraged by implementations other than Trafodion.
In transaction processing, databases, and computer networking, the two-phase commit protocol (2PC) is a type of atomic commitment protocol (ACP). ... The protocol achieves its goal even in many cases of temporary system failure (involving either process, network node, communication, etc. failures), and is thus widely used.
Transactions and Concurrency Control in distributed systems. Transaction properties, classification, and transaction implementation. Flat, Nested, and Distributed transactions. Inconsistent Retrievals, Lost Update, Dirty Read, and Premature Writes Problem

Reactive by example - at Reversim Summit 2015Eran Harel
Explaining the reactive manifesto by a real world case study.
This is a cool story about the evolution of our monitoring infrastructure. From the naive approach to a super resilient system.
How do we manage to handle 4M metrics / minute, and over 1K concurrent connections?
What strategies did we try to apply and where did it fail?
What are the techniques and technologies we use in order to achieve this?
How do we handle errors, and failures at this scale?
What can we still improve?
Operating system 23 process synchronizationVaibhav Khanna
Processes can execute concurrently
May be interrupted at any time, partially completing execution
Concurrent access to shared data may result in data inconsistency
Maintaining data consistency requires mechanisms to ensure the orderly execution of cooperating processes
Illustration of the problem:Suppose that we wanted to provide a solution to the consumer-producer problem that fills all the buffers. We can do so by having an integer counter that keeps track of the number of full buffers. Initially, counter is set to 0. It is incremented by the producer after it produces a new buffer and is decremented by the consumer after it consumes a buffer

Launch Your Streaming Platforms in MinutesRoshan Dwivedi
The claim of launching a streaming platform in minutes might be a bit of an exaggeration, but there are services that can significantly streamline the process. Here's a breakdown:
Pros of Speedy Streaming Platform Launch Services:
No coding required: These services often use drag-and-drop interfaces or pre-built templates, eliminating the need for programming knowledge.
Faster setup: Compared to building from scratch, these platforms can get you up and running much quicker.
All-in-one solutions: Many services offer features like content management systems (CMS), video players, and monetization tools, reducing the need for multiple integrations.
Things to Consider:
Limited customization: These platforms may offer less flexibility in design and functionality compared to custom-built solutions.
Scalability: As your audience grows, you might need to upgrade to a more robust platform or encounter limitations with the "quick launch" option.
Features: Carefully evaluate which features are included and if they meet your specific needs (e.g., live streaming, subscription options).
Examples of Services for Launching Streaming Platforms:
Muvi [muvi com]
Uscreen [usencreen tv]
Alternatives to Consider:
Existing Streaming platforms: Platforms like YouTube or Twitch might be suitable for basic streaming needs, though monetization options might be limited.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
