What is the best
NoSQL product to scale out?
• There are many flavours of NoSQL: 
• Key/Value
• Documents
• Column-oriented
• Objects

www.percona.com
When consider scale out?
• Workset bigger than RAM
• High CPU usage
• Disk O/I exhausted
• Redundancy
• Decrease Latency

www.percona.com
Let's talk about MongoDB
• A few things that you need to know before
scale MongoDB: 
• MongoDB has a single master for each
replicaset. 
• Sharding must be very well configured,
otherwise you will only have a few
machines idle.  
• Look at what you want to scale:
• reads?
• writes?

www.percona.com
Let's talk about MongoDB
• High consistence will cost more time to
confirm a operation. 
• Downsize is not so easy operation all data
will be removed by one single thread, by
design. 
• Keep your eyes open to  
MongoS and Config Servers  
those guys are responsible to  
keep a shard working.

Random thoughts on sql server performance

Nigel Foulkes-Nock

When done correctly Serverless offers fantastic potential but can also lead to spectacular failure when critical concepts are overlooked. With over a dozen Serverless implementations on Azure Functions over the last couple years, I’ve learned some lessons the hard way. In this talk, I will be sharing a few of the most impactful hard-earned lessons and how I was able to overcome them. I’ll be touching on topics ranging from considerations using traditional relational databases, managing service and data connections to managing complexity and increasing observability. The talk is done in the context of Azure Functions but whose concepts apply equally to all Serverless Platforms.

Enterprise Search is a challenging problem for most organizations. Public search technologies such as Google can index content and use link popularity to rank content in addition to the basic keyword matches. Enterprise Search is different. Sometimes it requires specially designed indexes as well as several processing steps. At the U.S. Patent & Trademark Office, part of the Department of Commerce, a team of professionals is building the next generation of search tools using open source technologies. Like any large undertaking, it’s not a simple plug and play project. Main topics to be covered in this talk: + Architectures for Large Scale Enterprise Search + Leveraging Apache Cassandra & Spark + Customizing / Configuring Apache SolR and Indexing + Writing a custom Parser for SolR in Scala

Over the last year, how many times have you found yourself itching to implement that great new service? Then you start getting your hands dirty and notice that you have to make choices: time to market? reliability? performance? If you are running low on budget (as I usually am), the problem gets exponentially more complicated. In this talk, I am going to share some recent experiences I had on using the Go programming language to explore the free-tier of cloud providers to quickly develop web services without putting aside good performance, and reliability.

Microsoft has built a rich ecosystem around the various flavors of ASP.NET – MVC, Web API and even WebForms have a place in the modern web development world. So what the heck is up with ASP.NET Core anyways? Microsoft has flipped the ASP.NET world on its head with this fast, cross-platform web framework, designed from the ground up with developers from all walks of life in mind – and the change isn’t as scary as you think. In this session, we’ll learn about ASP.NET Core and its design philosophies. We’ll learn how to leverage several popular development tools frequently used by developers outside of the ASP.NET ecosystem, including Gulp, Bower, Node and NPM, to build and run our application. Finally, we’ll use Visual Studio Code to create and run our very first ASP.NET Core project (on a Mac no less!) For current ASP.NET developers, we’ll also touch on the portability of your current ASP.NET code.

Is your Kafka cluster keeping you up all night? URP driving you crazy? Do you want all the benefits of running Kafka as a shared data hub, but the thought of supporting that many clients on the same infrastructure has you spooked? We felt the same way, but it turned out Kafka can indeed be run at scale in a multi-tenant environment with the right mix of hardware, configuration, and filesystem sorcery. As we all know, a well rested administrator is a happy (less cranky) administrator. At Pandora we run a large shared Kafka cluster supporting thousands of clients and trillions of messages per day. Further, access to our cluster is intentionally permissive, lowering the bar to entry for users in order to promote innovation and speed to production. This approach has pros, but also, predictably, many cons. As the number of clients grew, we noticed periods of performance degradation at peak volume. This symptoms of this included thrashing ISR expands/shrinks, decreased throughput, and increased response times. We were initially baffled by this behavior and affectionately named it “The Thing.” This talk is the story of how we tracked this problem to its root by diving deep into both Kafka and ZFS, ultimately alleviating the issue with ZFS configuration, broker configuration, and end-user education (read: client scolding). This allowed us to support our current load – with room for growth – without the need for additional hardware.

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.

AI/ML Infra Meetup May. 23, 2024 Organized by Alluxio For more Alluxio Events: https://www.alluxio.io/events/ Speaker: - Lu Qiu (Data & AI Platform Tech Lead, @Alluxio) - Siyuan Sheng (Senior Software Engineer, @Alluxio) Speed and efficiency are two requirements for the underlying infrastructure for machine learning model development. Data access can bottleneck end-to-end machine learning pipelines as training data volume grows and when large model files are more commonly used for serving. For instance, data loading can constitute nearly 80% of the total model training time, resulting in less than 30% GPU utilization. Also, loading large model files for deployment to production can be slow because of slow network or storage read operations. These challenges are prevalent when using popular frameworks like PyTorch, Ray, or HuggingFace, paired with cloud object storage solutions like S3 or GCS, or downloading models from the HuggingFace model hub. In this presentation, Lu and Siyuan will offer comprehensive insights into improving speed and GPU utilization for model training and serving. You will learn: - The data loading challenges hindering GPU utilization - The reference architecture for running PyTorch and Ray jobs while reading data from S3, with benchmark results of training ResNet50 and BERT - Real-world examples of boosting model performance and GPU utilization through optimized data access
