DatabasesHow do you mix SQL and NoSQL worlds without starting a messy revolution?
David will start from a RestX, Hibernate and Postgresql/MySQL based application and will add a complete integration of Elasticsearch, all live from the stage during his presentation.
DatabasesWanna transform your documents on the fly before indexing them into elasticsearch? Node ingest is built for you.
The talk will also cover the reindex api, which can be used in combination with ingest pipelines to modify data while reindexing.
Last but not least, I'll tell you how to write your own Ingest processor in Java as a plugin! Our own processor will convert postal addresses from/to geo points.
DatabasesApache Kafka is a message broker that offers not only massive scalability and fault tolerance, but also unique guarantees around message ordering and delivery: relaying billing information, detecting security-related events, storing information at high-throughput. Kafka simplifies it all and gives developers a chance to rethink the data flows between components, moving information interchange into the center of their architectures.
DatabasesMySQL Replication is a widely used but little understood way of ensuring you have multiple copies of your database information. This session start with simple master/salve replication, walk through the row-based versus statement-based options, and build up to a highly available cluster using MySQL Group Replication. Find ways to tune your setting for peak efficiency while protecting your data.
DatabasesYou’ve mapped it out in Visio, put in place all the caching and gateways possible, flip the switch…and nothing. Your beautiful microservice architecture fell on its face! In this experience report, we will look at a failed microservice implementation and how we fixed it, from the ground up.
DatabasesPostgreSQL is well known being an object-relational database management system. In its core, PostgreSQL is schema-aware dealing with fixed database tables and column types. However, recent versions of PostgreSQL made it possible to deal with schema-free data. Learn which new features PostgreSQL supports and how to use those features in your PHP application.
DatabasesOnly 2% of developers have formal training in structured query language, relational theory, or even simple sets. Yet, they use a database to store data and wonder why their queries are so slow. This session covers what really happened when you submit a query, why you can not visually tell a poor query from a good one, how to skip the 'N+1" problems, and more. Do not be a slave to slow queries! Learn to become a minor database deity!
DatabasesConvert your entire database structure into a graph using reverse engineering on the database (foreign keys, indexes, etc). Why? The process opens up a whole world of possibilities from automating API exposure, Faceted Search, CRUD panel automation as well. It takes away at least 1/2 of the workload off compared to traditional back-ends. I will walk you through the process AND show the benefits. Potential unveiling of a framework called Backrub!
