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.
Solr cloud the 'search first' nosql database extended deep divelucenerevolution
Presented by Mark Miller, Software Engineer, Cloudera
As the NoSQL ecosystem looks to integrate great search, great search is naturally beginning to expose many NoSQL features. Will these Goliath's collide? Or will they remain specialized while intermingling – two sides of the same coin.
Come learn about where SolrCloud fits into the NoSQL landscape. What can it do? What will it do? And how will the big data, NoSQL, Search ecosystem evolve. If you are interested in Big Data, NoSQL, distributed systems, CAP theorem and other hype filled terms, than this talk may be for you.
The Proxy Wars - MySQL Router, ProxySQL, MariaDB MaxScaleColin Charles
As proxies (and database routers) go, the first one I ever used was the now deprecated MySQL Proxy. Since then, I've managed to use MariaDB MaxScale quite a bit (including its fork AirBnB MaxScale), played around with ProxySQL in recent time, and also started taking a look at MySQL Router. In this quick 20-minute overview, we'll discuss why these three exist, a feature comparison, and reasons when to use the right tool for the job.

Building Google-in-a-box: using Apache SolrCloud and Bigtop to index your big...rhatr
You’ve got your Hadoop cluster, you’ve got your petabytes of unstructured data, you run mapreduce jobs and SQL-on-Hadoop queries. Something is still missing though. After all, we are not expected to enter SQL queries while looking for information on the web. Altavista and Google solved it for us ages ago. Why are we still requiring SQL or Java certification from our enterprise bigdata users? In this talk, we will look into how integration of SolrCloud into Apache Bigtop is now enabling building bigdata indexing solutions and ingest pipelines. We will dive into the details of integrating full-text search into the lifecycle of your bigdata management applications and exposing the power of Google-in-a-box to all enterprise users, not just a chosen few data scientists.
This is my presentation on MySQL user camp on 26-06-2015.
It gives basic introduction to Ansible and how it can be benefited for MySQL deployment and configuration.
This was my second presentation taken on MySQL User Camp ( Bangalore ) held on Nov-08 2013. I have a made a presentation about the percona tools mostly used percona tools.
Databases require capacity planning (and to those coming from traditional RDBMS solutions, this can be thought of as a sizing guide). Capacity planning prevents resource exhaustion. Capacity planning can be hard. This talk has a heavier leaning on MySQL, but the concepts and addendum will help with any other data store.
Today you can use hosted MySQL/MariaDB/Percona Server in several "cloud providers" in what is considered using it as a service, a database as a service (DBaaS). You can also use hosted PostgreSQL and MongoDB thru various service providers. Learn the differences, the access methods, and the level of control you have for the various public cloud offerings:
- Amazon RDS for MySQL and PostgreSQL
- Google Cloud SQL
- Rackspace OpenStack DBaaS
- The likes of compose.io, MongoLab and Rackspace's offerings around MongoDB
The administration tools and ideologies behind it are completely different, and you are in a "locked-down" environment. Some considerations include:
* Different backup strategies
* Planning for multiple data centres for availability
* Where do you host your application?
* How do you get the most performance out of the solution?
* What does this all cost?
Growth topics include:
* How do you move from one DBaaS to another?
* How do you move all this from DBaaS to your own hosted platform?
Questions like this will be demystified in the talk. This talk will benefit experienced database administrators (DBAs) who now also have to deal with cloud deployments as well as application developers in startups that have to rely on "managed services" without the ability of a DBA.

Stream your Operational Data with Apache Spark & Kafka into Hadoop using Couc...Data Con LA
Abstract:-
Tracking user events as they happen can challenge anyone providing real time user interaction. It can demand both huge scale and a lot of processing to support dynamic adjustment to targeting products and services. As the operational data store Couchbase data services are capable of processing tens of millions of updates a day. Streaming through systems such as Apache Spark and Kafka into Hadoop, information about these key events can be turned into deeper knowledge. We will review Lambda architectures deployed at sites like PayPal, Live Person and LinkedIn that leverage a Couchbase Data Pipeline.

OpenStack Days East -- MySQL Options in OpenStackMatt Lord
In most production OpenStack installations, you want the backing metadata store to be highly available. For this, the de facto standard has become MySQL+Galera. In order to help you meet this basic use case even better, I will introduce you to the brand new native MySQL HA solution called MySQL Group Replication. This allows you to easily go from a single instance of MySQL to a MySQL service that's natively distributed and highly available, while eliminating the need for any third party library and implementations.
If you have an extremely large OpenStack installation in production, then you are likely to eventually run into write scaling issues and the metadata store itself can become a bottleneck. For this use case, MySQL NDB Cluster can allow you to linearly scale the metadata store as your needs grow. I will introduce you to the core features of MySQL NDB Cluster--which include in-memory OLTP, transparent sharding, and support for active/active multi-datacenter clusters--that will allow you to meet even the most demanding of use cases with ease.
Although it may sound like an oxymoron, the key to scaling a MySQL platform truly lies in consolidation of the physical storage layer. Whether you are running a dozen or a thousand MySQL instances, SolidFire provides a pathway to horizontally scale the storage layer, enabling capital and operational cost reductions, while virtually eliminating maintenance and replica deployment windows.

Azure Database for MySQL is a managed database cluster within Microsoft Azure Cloud that runs MySQL community edition. There are really two deployment options: “Single Server” and “Flexible Server (Preview).” We will look at the Flexible Server version, even though it is still preview, because most enterprise applications require failover, so this is the relevant comparison for Tungsten Clustering.
You may use Tungsten Clustering with native MySQL, MariaDB or Percona Server for MySQL in GCP, AWS, Azure, and/or on-premises data centers for better technological capabilities, control, and flexibility. But learn about the pros and cons!

The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing.
One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

7. Scaling MySQL
Scaling reads using replication.
• Replication is the best solution.
• Replication is Async.
• Failover has to be set.
• Single writer
Write Queries Read Queries
8. Scaling MySQL
Scaling reads using Galera
• Read/ Write on any node
• Synchronous Replication
• A good HA solution.
• Easy to add nodes.
Write / Read
Queries
9. Scaling MySQL
Scaling Writes
• Replication can’t scale writes
• Partitioning is needed.
• Distributes the writes
• Horizontal scaling or Sharding.
ID 1 - 1000 ID 1001 - 2000
10. Scaling MySQL
Components .
•Shard Key
– Range
– Hash
– List
•Meta data store
•Managing data set
•High Availability of shards.
•Database and schema changes.
11. Scaling MySQL
Sharding Architecture
Proxy layer

Shard B
Shard C
Application
12. Scaling MySQL
Advantages of Sharding
•Improved Performance
•Smaller Data set on local node.
•Handling large data set
•Scale well horizontally.
•Only small data set is affected on a node failure.
Disadvantages of Sharding
•Managing the shards
•Code change is need at some cases.
•Splitting Shards
•Maintaining the HA
13. Available Sharding Tools
• Sharding is used widely in Large Scale MySQL Deployments.
• Large organization built their own tools for sharding.

2) Jetpants (Tumblr )
3) Vitess ( Youtube )
4) MySQL Fabric ( Oracle MySQL )
16. MySQL FABRIC
• MySQL Fabric is the frame work to maintain shards and High Availability.
• Downloaded from MySQL Utilities.
• Good CLI commands.
• Works on MySQL > 5.6.10
• XML RPC for Python , php and Java.
• Minimized downtime of shard.

Advantages:
• Ease of Failover with GTID.
• Shard Split is easy
• RPC avoid network hops.
Dis Advantages
• Fabric node will be single point of failure
• No Cross Shard . ( Shard query can help here)
• Limited Connectors.
