AppSphere 15 - Is the database affecting your critical business transactions?AppDynamics
Databases are fundamental to every application, and reading or writing data in a quick and reliable way is critical to ensuring happy users. Your shiny new application may have worked well in the beginning, but with more and more people using the app the response times may take a nose dive. Or, what if you push a great new feature, guaranteed to make customers happy, but then it doesn’t scale or it actually degrades the performance of existing functionality? What do you do? How do you diagnose and resolve these issues in a timely and cost efficient manner?
Whilst many organizations employ a team of database administrators (DBAs) to manage database performance, it’s often a group separated from development and operational support with their own tools, scripts, and procedures. This creates inefficiency in the root cause analysis process. We want to empower customers by including deep-dive database monitoring as part of end-to-end APM, thereby providing immediate visibility of DB metrics to all groups within IT.
This session covers:
-Why it makes sense to include the database as part of API
-What are some real world problems affecting database performance
-What is a good methodology for diagnosing and understanding database performance
This deck was originally presented at AppSphere 2015.
Task allocation on many core-multi processor distributed systemDeepak Shankar
Migration of software from a single to multi-core, single to multi-thread, and integrated into a distributed system requires a knowledge of the system and scheduling algorithms. The system consists of a combination of hardware, RTOS, network, and traffic profiles. Of the 100+ popular scheduling algorithms, the majority use First Come-First Server with priority and preemption, Weight Round Robin, and Slot-based. The task allocation must take into consideration a number of factors including the hardware configuration, the RTOS scheduling, task dependency, parallel partitioning, shared resources, and memory access. Additionally, embedded system architectures always have the possibility of using custom hardware to implement tasks that may be associated with Artificial Intelligence, diagnostic or image processing.
In this Webinar, we will show you how to conduct trade-offs using a system model of the tasks and the target resources. You will learn to make decisions based on the hardware and network statistics. The statistics will assist in identifying deadlocks, bottlenecks, possible failures and hardware requirements. To estimate the best task allocation and partitioning, a discrete-event simulation with both time- and quantity-shared resource modeling is essential. The software must be defined as a UML or a task graph.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

"Choosing proper type of scaling", Olena SyrotaFwdays
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.
Discover the Unseen: Tailored Recommendation of Unwatched ContentScyllaDB
The session shares how JioCinema approaches ""watch discounting."" This capability ensures that if a user watched a certain amount of a show/movie, the platform no longer recommends that particular content to the user. Flawless operation of this feature promotes the discover of new content, improving the overall user experience.
JioCinema is an Indian over-the-top media streaming service owned by Viacom18.
ScyllaDB is making a major architecture shift. We’re moving from vNode replication to tablets – fragments of tables that are distributed independently, enabling dynamic data distribution and extreme elasticity. In this keynote, ScyllaDB co-founder and CTO Avi Kivity explains the reason for this shift, provides a look at the implementation and roadmap, and shares how this shift benefits ScyllaDB users.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
