Overview of the new JSON processing functionality in MySQL: the new JSON type, the in-line JSON path expressions, the JSON functions and how to go about indexing JSON
Cassandra 3.0 - JSON at scale - StampedeCon 2015StampedeCon
This session will explore the new features in Cassandra 3.0, starting with JSON support. Cassandra now allows storing JSON directly to Cassandra rows and vice versa, making it trivial to deploy Cassandra as a component in modern service-oriented architectures.
Cassandra 3.0 also delivers other enhancements to developer productivity: user defined functions let developers deploy custom application logic server side with any language conforming to the Java scripting API, including Javascript. Global indexes allow scaling indexed queries linearly with the size of the cluster, a first for open-source NoSQL databases.
Finally, we will cover the performance improvements in Cassandra 3.0 as well.
Slick: Bringing Scala’s Powerful Features to Your Database Access Rebecca Grenier
This talk will teach you how to use Slick in practice, based on our experience at EatingWell Media Group. Slick is a totally different (and better!) relational database mapping tool that brings Scala’s powerful features to your database interactions, namely: static-checking, compile-time safety, and compositionality.
Here at EatingWell, we have learned quite a bit about Slick over the past two years as we transitioned from a PHP website to Scala. I will share with you tips and tricks we have learned, as well as everything you need to get started using Slick in your Scala application.
I will begin with Slick fundamentals: how to get started making your connection, the types of databases it can access, how to actually create table objects and make queries to and from them. We will using these fundamentals to demonstrate the powerful features inherited from the Scala language itself: static-checking, compile-time safety, and compositionality. And throughout I will share plenty of tips that will help you in everything from getting started to connection pooling options and configuration for use at scale.
At Ullink, our java heap are usually pretty large (up to 256GB) and we are dealing with large volume of data. But most of the space consumed in the heap are not business data as we may intuitively think, it is data structures!
In this presentation I would like to show you what are the cost of java objects, and the usual suspects in our data structures (Lists, Maps, Strings) and what we can do about this.

Since launch, this current version of MySQL have new features such as: JSON Data Type and Generated/Virtual Columns,. If your application is breaking when you upgrade to 5.7, the new GROUP BY default may be the reason, learn here how to properly address that issue and keep your data consistent, how to index JSON data type and when to use generated columns.
CQL performance with Apache Cassandra 3.0 (Aaron Morton, The Last Pickle) | C...DataStax
The 3.0 storage engine re-write is the biggest and most exciting change to ever happen in Apache Cassandra. The new storage engine can efficiently store and read data from disk using the same concepts present in the CQL 3 language. This has delivered large space savings, and creates new performance characteristics.
In this talk Aaron Morton, Co Founder at The Last Pickle and Apache Cassandra Committer, will discuss the 3.0 storage engine, it's layout and performance characteristics.

Data modeling is hard, especially in the world of distributed NoSQL stores. With relational databases, developers have tended to store normalized data and shape their query model around that structure. This can come back to bite you when it comes time to scale, as complex queries across dozens of tables begin to affect application performance. It’s common to find developers rethinking their data model as query latency increases under load.
With NoSQL stores, developers must consider their query patterns from the outset of application development, designing their data model to fit those patterns. A number of techniques, new and old, can be used to allow for maximum performance and scalability.
Topics covered will include: De-normalization, time boxing, conflict resolution, and convergent & commutative replicated data types. Additionally, discussions of common query patterns in light of the capabilities of various NoSQL data stores will be reviewed.

The new JSON fields are some of the most talking about new features in MySQL 5.7. But they are by no means the only awesome things this version has to offer. MySQL 5.7 is a year old, so this talk won't be an introduction to this version. We will be digging into 5.7 to see how to make the most of the tools available in it. Want to tackle important practical problem solving for your data, make your query performance analysis more efficient or look at how virtual columns can help you index data? This talk is for you!
Longhorn PHP - MySQL Indexes, Histograms, Locking Options, and Other Ways to ...Dave Stokes
Slow query? Add an index or two! But things are suddenly even slower! Indexes are great tools to speed data lookup but have overhead issues. Histograms don’t have that overhead but may not be suited. And how you lock rows also effects performance. So what do you do to speed up queries smartly? This is a clear, detailed look at what you can do to really speed up your queries in a logical, orthogonal process. Updated Presentation for Longhorn PHP Conference October 14th, 2021

Modern query optimisation features in MySQL 8.Mydbops
MySQL 8 (a huge leap forward), indexing capabilities, execution plan enhancements, optimizer improvements, and many other current query tweak features are covered in the slides.
The JSON data type and functions that support it comprise one of the most interesting features introduced in MySQL 5.7 for application developers. But no feature is a Golden Hammer. We need to apply a little expertise to get the best of it, and avoid misusing it. I’ll show practical examples that work well with JSON, and other scenarios where conventional columns would perform better. Questions addressed in this presentation: How much space does JSON data use, compared to conventional data? What is the performance of querying JSON vs. conventional data? How do I create indexes for JSON data? What kind of data is best to store in JSON? How do I get the best of both worlds?
JSON is an important datatype transporting data between servers and many modern applications. Postgres has been at the forefront of bringing these capabilities into the hands of database users. JSONB data type allows for faster operations within PostgreSQL.
At this webinar we will look at:
- How to use JSON from applications
- How to store it in the database
- How to index JSON data
- Tips and tricks to optimize usage
We then closed with a review of the roadmap for new PostgreSQL features for JSON and JSON standards compliance.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.
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.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

Create an index on type field, first create a virtual column by extracting the type field, and then create an index on this virtual column.
Run the same query as before. Execution time goes 1.25 sec down to 0.06 sec.
Still has to examine full index, but now it is just an index of the values all extracted. It is much smaller.
