RavenDB 3.5
RavenDB 3.5Oren Eini From the new consensus based clustering to active data exploration, RavenDB 3.5 contains quite a lot of new features, improvement and fixes. In this keynote Oren Eini will showcase RavenDB 3.5 new features. Including SLAs, I/O monitoring, improved performance and stability, smarter replication, and more.
RavenDB embedded at massive scales
RavenDB embedded at massive scalesOren Eini 1) RDI uses RavenDB embedded in over 36,000 restaurants with around 500,000 individual machines processing $50,000 per second in payments.
2) RavenDB allows for unit testing without mocking the database, advanced statistics on data persistence, and transparent replication with high availability.
3) The challenges of using RavenDB on specialized older hardware with low memory and ESENT include fine-tuning memory usage, disabling caching, and automating recovery from unclean shutdowns with ESENTUTL.EXE.
RavenDB 4.0
RavenDB 4.0Oren Eini Oren Eini discusses the next major version of RavenDB 4.0, running on the CoreCLR, and skim over topics of performance (much higher), flexibility and ease of use.
Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDB
Zapping ever faster: how Zap sped up by two orders of magnitude using RavenDBOren Eini
Join a real uplift experience with Hagay Albo, the CTO of the Zap/Yellow Page Group in Israel, in which he explains how his team was able to take a legacy (slow and hard to modify) group of sites and make them easier to work with, MUCH faster and greatly simplified the operational environment.
By prioritizing high availability, flexible data modeling and focusing on raw speed Zap was able to reduce its load times by Two Orders of Magnitudes. Using RavenDB as the core engine behind Zap's new sites had improved site traffic, reduced time to market and made it possible to implement the next-gen features that were previously beyond reach.
Stack Exchange Infrastructure - LISA 14
Stack Exchange Infrastructure - LISA 14GABeech The Stack Exchange infrastructure supports 560 million page views and 34TB of data transferred per month across 1665 requests per second on average. To ensure high performance, Stack Exchange uses load balancers, web servers, caching, and databases in a redundant configuration. Careful performance monitoring and optimization has resulted in homepage and question page render times of 52ms and 33ms respectively.
Know thy cost (or where performance problems lurk)
Know thy cost (or where performance problems lurk)Oren Eini Performance happens. Whether you're designed for it or not it doesn’t matter, she is always invited to the party (and you better find her in a good mood). Knowing the cost of every operation, and how it distributes on every subsystem will ensure that when you are building that proof-of-concept (that always ends up in production) or designing the latest’s enterprise-grade application; you will know where those pesky performance bugs like to inhabit. In this session, we will go deep into the inner working of every performance sensitive subsystem. From the relative safety of the client to the binary world of Voron.
Drupal High Availability High Performance 2012
Drupal High Availability High Performance 2012Amazee Labs This document discusses strategies for achieving high availability and high performance with Drupal. It recommends using redundant web and database servers, load balancers, caching with Varnish and Memcache, and a distributed file system like GlusterFS. MySQL master-slave replication is suggested for database redundancy. The goal is a scalable system with no single point of failure and fast response times.
Lessons from the Trenches - Building Enterprise Applications with RavenDB
Lessons from the Trenches - Building Enterprise Applications with RavenDBOren Eini It's easy, fun, and simple to get a prototype application built with RavenDB, but what happens when you get to the point of shipping v1.0 into Production? Many of the subtle decisions made during development can have undesirable consequences in Production. In this session, Dan Bishop will explore some of the pain points that arise when building, deploying, and supporting enterprise-grade applications with RavenDB.
SSDs are Awesome
SSDs are AwesomeBarry Abrahamson 1) SSDs provide significantly better performance than HDDs for WordPress.com, reducing costs by 75% while improving performance and capacity 6 times.
2) An experiment replacing HDD RAID with SSDs was very successful, but initial production deployment had critical bugs and required restarting the migration process.
3) While SSDs save money and users' time, maximizing their performance requires substantial research, testing, and software optimization from system administrators.
Capacity Planning
Capacity PlanningMongoDB Deploying MongoDB can be a challenge if you don't understand how resources are used nor how to plan for the capacity of your systems. If you need to deploy, or grow, a MongoDB single instance, replica set, or tens of sharded clusters then you probably share the same challenges in trying to size that deployment. This talk will cover what resources MongoDB uses, and how to plan for their use in your deployment. Topics covered will include understanding how to model and plan capacity needs from the perspective of a new deployment, growing an existing one, and defining where the steps along scalability on your path to the top. The goal of this presentation will be to provide you with the tools needed to be successful in managing your MongoDB capacity planning tasks.

Let's face it, testing distributed systems is hard. Large number of inputs, partial failures, and asynchrony make these systems seemingly impossible to verify. Formal testing methods are onerous and system correctness continues to elude us. Despite the difficulty, we need to have a way to change our systems with confidence. Integration and unit tests are vital to our sanity and we know it's good for us to use continuous integration to ensure functional consistency across our products.
Come to this talk for a fresh and practical look into the various aspects of distributed systems testing and integration. We will cover CI pipelines: their strengths, weaknesses, and ways to improvement them. Get ready to rediscover the untapped power of your integration practices and develop a burning desire to make them more awesome!

Computational Patterns of the Cloud - QCon NYC 2014
Computational Patterns of the Cloud - QCon NYC 2014Ines Sombra This document summarizes a presentation about computational patterns in the cloud. It discusses four key patterns: reclaimable resources, where cloud applications provision resources on demand and release them when not needed; harvesting services, where applications consume external services via APIs rather than maintaining standalone components; distributed systems, where resources and services come together to form distributed systems as the new norm; and continuous everything, where the cloud enables continuous delivery, deployment, and testing practices. The document provides examples and stories about implementing these patterns and discusses challenges organizations may face in adopting cloud-native approaches.

Transitioning From SQL Server to MySQL - Presentation from Percona Live 2016
Transitioning From SQL Server to MySQL - Presentation from Percona Live 2016Dylan Butler What if you were asked to support a database platform that you had never worked with before? First you would probably say no, but after you lost that fight, then what? That is exactly how I came to support MySQL. Over the last year my team has worked to learn MySQL, architect a production environment, and figure out how to support it alongside our other platforms (Microsoft SQL Server and Oracle). Along the way, I have also come to appreciate the unique offering of this platform and see it as an important part of our environment going forward.
To make things even more challenging, our first MySQL databases were the backend for a critical, web based application that needed to be highly available across multiple data centers. This meant that we did not have the luxury of standing up a simpler environment to start with and building confidence there. Our final architecture ended up using a five node Percona XtraDB Cluster spread across three data centers.
This session will focus on lessons learned along the way, as well as challenges related to supporting more than one database platforms. It should be interesting to anyone who is new to MySQL, anyone who is being asked to support more than one database platform, or anyone who wants to see how an outsider views the platform.

Batch to near-realtime: inspired by a real production incident
Batch to near-realtime: inspired by a real production incidentShivji Kumar Jha This slide deck was used for the platformatory streams meetup in Bengaluru on July 7, 2024.
This is a real world account from an Apache Druid cluster in production. A story of 48 hours of debugging, learning and understanding batch vs stream better, filing a couple of issues in Druid open source projects and finally a stable production pipeline again thanks to the Druid community. We will discuss what parts of your design could be impacted, how you should change the related systems so the cascading failures don’t bring down your complete production availability. As an example, we will discuss the bottlenecks we had in overlord, slot issues for Peons in middle managers, coordinator bottlenecks, how to mitigated task and segment flooding, what configs we changed sprinkled with real world numbers and snapshots from our Grafana dashboards.
Finally we will list all the leanings and how we made sure we never repeat the same mistakes in production systems.

A Case Study of NoSQL Adoption: What Drove Wordnik Non-Relational?
A Case Study of NoSQL Adoption: What Drove Wordnik Non-Relational?DATAVERSITY Wordnik migrated from a MySQL relational database to the non-relational MongoDB database for 5 key reasons: speed, stability, scaling, simplicity, and fitting their object model better. They tested MongoDB extensively, iteratively improving their data mapping and access patterns. The migration was done without downtime by switching between the databases. While inserts were much faster in MongoDB, updates could be slow due to disk I/O. Wordnik addressed this through optimizations like pre-fetching on updates and moving to local storage. Overall, MongoDB was a better fit for Wordnik's large and evolving datasets.

Agile Oracle to PostgreSQL migrations (PGConf.EU 2013)
Agile Oracle to PostgreSQL migrations (PGConf.EU 2013)Gabriele Bartolini Migrating an Oracle database to Postgres is never an automated operation. And it rarely (never?) involve just the database. Experience brought us to develop an agile methodology for the migration process, involving schema migration, data import, migration of procedures and queries up to the generation of unit tests for QA.
Pitfalls, technologies and main migration opportunities will be outlined, focusing on the reduction of total costs of ownership and management of a database solution in the middle-long term (without reducing quality and business continuity requirements).

Data antipatterns NYC Devops - 2014
Data antipatterns NYC Devops - 2014Ines Sombra Are you running a Database in the cloud? Worried that you’re doing it wrong?
Engine Yard supports a broad set of databases, with lots of
flexibility for customers to modify and configure their installations. But the freedom to adapt and extend standard functionality comes at the risk of unexpected negative consequences: seemingly benign modifications can seriously affect durability and performance.
During our years of helping customers, I've had the unique opportunity to observe common problems, patterns, and best practices with big (and not so big) data. In this talk I'll highlight the most common pitfalls and tell you how to avoid them (I will most likely rant about other things too!).

How the Cloud is changing the world
How the Cloud is changing the worldInes Sombra In October 2013 I stopped by Lancaster University's Highwire program to give a seminar on the Cloud and industry disruptions.
Abstract:
Everyone is talking about The Cloud. From disrupting the way we do business to the way we live our lives, it has undoubtedly shifted the way we think about computing, IT operations, innovation, and entrepreneurship. But how should we think about it and why has it brought a paradigm change? What specific technologies can we leverage to improve our lives and how will the next iteration of cloud-based systems look like?
In this seminar, I will introduce you to cloud computing’s history and discuss its applications with practical examples from Engine Yard’s customers, peers, and partners.

Getting started with Riak in the Cloud
Getting started with Riak in the CloudInes Sombra Getting started with Riak in the Cloud involves provisioning a Riak cluster on Engine Yard and optimizing it for performance. Key steps include choosing instance types like m1.large or m1.xlarge that are EBS-optimized, having at least 5 nodes, setting the ring size to 256, disabling swap, using the Bitcask backend, enabling kernel optimizations, and monitoring and backing up the cluster. Benchmarks show best performance from high I/O instance types like hi1.4xlarge that use SSDs rather than EBS storage.
Riak at Engine Yard Cloud
Riak at Engine Yard CloudInes Sombra The document discusses using Riak, an open source NoSQL database, in the cloud to provide highly available and fault tolerant storage for applications. It describes how the authors' application struggled with availability when hosted on AWS, and their research led them to choose Riak as a solution. Riak provides features like consistent hashing, hinted handoff, and active anti-entropy that allow it to scale linearly and remain available even during failures or added/reduced nodes. The document provides guidance on deploying a Riak cluster in the cloud, including choosing instance types, sizing the cluster, disabling swap, using the right filesystem and scheduler, and monitoring and scaling the cluster over time.
North Bay Ruby Meetup 101911
North Bay Ruby Meetup 101911Ines Sombra This document provides an introduction to relational databases, NoSQL databases, and data in general. It includes the following:
- An overview of relational databases and their ACID properties. Relational databases are best for structured, centralized data and scale vertically.
- A survey of several popular NoSQL databases like MongoDB, Cassandra, Redis, and HBase. NoSQL databases are best for unstructured, large quantities of data and scale horizontally.
- General advice that the data and query models, durability needs, scalability needs, and consistency requirements should determine the best database choice. Trying different options is recommended.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock Building 10x Organizations with Modern Productivity Metrics
10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’
Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.
But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
