Quarkus 1.0 and SpringBoot

An airhacks.fm conversation with Dimitris Andreadis (@dandreadis) about: eclipsecon, Quarkus 1.0 and 1.0.1 releases, Quarkus is 8 months young, more extensions, more reactive functionality, 97 external committers and 93 RedHat committers, opinionated view vs. expansion and experimentation, Quarkus long term support, the three levels of extensions, quarkus extensions registry, the idea of composite extensions, emulating the composite extensions with a no-op extension, emulating the "all" injection setting in beans.xml, Quarkus uses Jandex for annotation searching, there is no greenfield development, many new developers are coming from SpringBoot, Kubernetes Native Spring apps on Quarkus by Georgios Andrianakis, Vodafone Greece replaces SpringBoot with Quarkus, the business case of SpringBoot to Quarkus migration was RAM consumption, boot time improvement with Quarkus, J9 JVM improves startup time, external dependencies are bad for startup time, Quarkus power is Java optimization, Quarkus optimises the standard Java HotSpot application, GraalVM optimizes it even further, Quarkus performs Hibernate optimizations at build time and not deployment time, Quarkus does not include SpringBoot library, Quarkus provides a Spring API compatibility layer which is converted at build time, Spring is emulated on Quarkus, the Spring compatibility layer was implemented in a month, Quarkus is built on 20 years old wisdom like Hibernate or Transaction Manager etc, in the Vodafone case, Quarkus reduced 60% of RAM, with memory savings come cost savings, the fast boot time is important for scaling in the clouds, Quarkus is comparable to React -- comes with free memory improvements without migrations, Quarkus ships with Vert.x, the Quarkus Vault extension, the SpringBoot compatibility layer is conceptually similar to Linux Wine compatibility layer, Quarkus would like to stay away from EJB, EJBs are faster than CDI on regular application servers on Quarkus the performance could be comparable with RequestScoped, Quarkus ships with built-in CORS filter, Keycloak supports oauth flows with a Gateway (Gatekeeper), Quarkus comes with native JWT Microprofile support, two Quarkus books are in the pipeline, keeping the conventions and usability of Quarkus could become a challenge, Quarkus will also come with tight OpenShift integration, the Engineering Director of the Extended Quarkus Team Dimitris Andreadis on twitter: @dandreadis and dandreadis.blogspot.com

Modules, Interfaces and Microservices

An airhacks.fm conversation with Mark Struberg (@struberg) about: Mark loves microservices, "if all you have is a hammer, everything looks like a nail", by Abraham Maslow, Hype Driven Development, the right size of a Microservice, splitting an application with Apache Maven, interfaces and DTOs, structuring a monolith, the killer argument against modules, interfaces with a single implementation, what if all the modules have the same version, testing against interfaces, pure unit tests are problematic in microservice world, avoid testing mocks, most problems and errors are in the database, System Tests in production-near environment over CDI Unit, Arquillian and Delta Spike, the overhead of Kubernetes, there are projects which require scaling others do not have such requirements, KVM over Kubernetes, testing locally vs. in production-like environment, Kubernetes is not only about load and scaling, Kubernetes is about management and sysadmins productivity, the main problem in business projects is overengineering, "Anything that can go wrong will go wrong": Murphy's Law, 200 errors per second, coursing about EJB and Java Enterprise, back to synchronous programming, transaction optimizations could be problematic, generating superfluous code with lombok, the "open session in view" pattern, transactions on JSF actions, in many use cases transactions are started on a too deep level, SOA and transaction boundaries, the fallacies of distributed computing, even larger projects have 10 microservices at most, there is no big company with a single, big monolith, staying local comes with the comfort of transactions, large amount of microservices is problematic, in 5 years we are going to reeingineer microservices into something different, everyone hates SOA now, everyone loved SOA back then, the saga pattern and compensating transactions, Jeff Bezos note on microservices from 2002, the benefits of microservices, the big bang Jakarta EE migration, the automatic package transformation with classloader, runnning old JARs on new namespaces, MicroProfile moves and iterates faster, Jakarta EE's release cadence is less frequent, the definition of "done" and micro frontends: Mark Struberg on twitter: @struberg and github: https://github.com/struberg.

Helidon: Never Block The Thread

An airhacks.fm conversation with Tomas Langer (@langer_tomas) about: The first line of code was in Basic on Atari 800 XE in 1989, computer club for kids in Prague, the programming accident in Java, studying and working for 16h a day, early interests in application servers, joining BEA Systems in 2003 and starting with version 6, the weblogic.jar and the weblogic "thin client" jar, the only BEA consultant in eastern Europe, Oracle's acquisition was a big change, leaving Oracle and moving to AVG for building custom application servers, starting at HomeCredit to develop with WebLogic, service buses and Co., joining a JavaONE conference session with Josh Long about SpringBoot, what is the purpose of FatJARs, one application per server, WebLogic became bigger over time, hollow JARs are explainable, about the costs of running application servers in the cloud, the deconstruction of the application server, how clustering became obsolete, application servers and docker layers, separation of business logic and infrastructure, the superfluous deployment machinery, the idea of a single application, the complicated application server's classloading, helidon only relies on the system ClassLoader, cloud features without clouds, starting at Oracle again, Airport, Prime, J4C and Helidon, helidon was fully opensourced in February, 2019, the origin Helidon idea was to be a cloud platform, Helidon's security is similar to WebLogic 8-9 security model, helidon separates between the user and service accounts, helidon's outbound security is automated, helidon was designed with docker in mind, helidon supports hollow jars and so directly the Docker layering, FatJARs are not worth the trouble, bare metal is the killer use case for FatJARs, hardcore classloaders are problematic with GraalVM, Helidon supports MicroProfile 3.0 all parts of it, merging all infrastructural modules in a single JAR is dangerous - beans.xml and class clashes are possible, helidon comes with JWT support fo outbound communication, in helidon you can provide you own main method, helidon comes with two modes: MicroProfile and Java SE, helidon is just a set of libraries, one library happens to be the server -- but is optional, helidon started as a Java SE platform only - microprofile came later, helidon was inspired by expressjs, trying to replicate the express experience, helidon ported the Java 9 flow API to Java 8 (by renaming the package) to backport the user experience, helidon uses the event loop of netty - never block the thread, most of Jakarta EE and Java SE libraries are not reactive, Java SE and MicroProfile modes can be used at the same time, helidon Java SE application is directly compilable with GraalVM to native image, Helidon 2.0 will come with native compilation support of MicroProfile, commercial support for Helidon will be probably possible, Helidon team answers questions on slack channel, no-one is interested in providing support of outdated software, MicroProfile is volatile - backward compatibility can be a challenge, Tomas Langer on twitter: @langer_tomas and on github: https://github.com/tomas-langer

DBs-ium, CDC and Streaming

An airhacks.fm conversation with Gunnar Morling (@gunnarmorling) about: The first Debezium commit, Randal Hauch, DBs-iuim, Java Content Repository JCR / modshape, exploring the Change Data Capture (CDC), how Debezium started, the MySQL binlog, the logical decoding in Postgres, Oracle Advanced Queuing, update triggers, Java Message System (JMS), there is no read detection, switching the current user at JDBC connection for audit purposes, helping Debezium with additional metadata table, using Kafka Streams to join the metadata and the payload, installing the logical decoding plugins into PostgreSQL, logical decoding plugin exposes the data from the write ahead log, decoding into protocol buffers with decoderbufs, in cloud environments like e.g. Amazon RDS you are not allowed to install any plugins, wal2json is verbose but comes preinstalled on RDS, pgoutput is responsible for the actual decoding of the events, debezium only sees committed transactions, debezium is mainly written in Java, decoderbufs was written by community and included to debezium, Debezium communicates with Postgres via the JDBC / Postgres API, pgoutput format is converted into Kafka Connector source format, Kafka Connect is a framework for running connectors, Kafka Connect comes with sink and source connectors, Kafka Connect comes with connector specific connectors like e.g. StringConverter, Converters are not Serializers, Debezium ships as Kafka Connect plugin, Kafka Connector runs as standalone process, running Debezium in embedded mode, JPA cache invalidation with Debezium, converting Debezium events into CDI events, converting database changes to WebSockets events, database polling vs the Debezium approach, DB2 will support Debezium, Oracle support is "on the horizon", Oracle LogmMiner, Oracle XStream, Debezium supports Microsoft SQL Server (starting with Enterprise license), Apache Pulsar comes with Debezium out-of-the-box, Pulsar IO, running Debezium as standalone service with outbounds APIs, MongoDB supports the "Debezium Change Event Format", Kafka Sink connectors are easy to implement, Debezium embedded mode and offsets, embedded connector has to remember the offset, an offset API is available for embedded Debezium connectors, combining CDC with Kafka Streams, Quarkus supports Kafka Streams and Reactive Messaging, Quarkus and Kafka Streams, Quarkus supports Kafka Streams in dev mode, replacing Hibernate Envers with Debezium, Messaging vs. Streaming or JMS vs. Kafka, Kafka is a database, the possible Debezium features, Cassandra support is coming, Outbox pattern is going to be better supported, transactional event grouping, dedicated topic for transaction demarcations, commercial support for Debezium, Debezium exposes JMX metrics, Five Advantages of Log-Based Change Data Capture, Reliable Microservices Data Exchange With the Outbox Pattern, Automating Cache Invalidation With Change Data Capture Gunnar Morling on twitter: @gunnarmorling and github: https://github.com/gunnarmorling.

Helidon: Never Block The Thread

An airhacks.fm conversation with Tomas Langer (@langer_tomas) about: The first line of code was in Basic on Atari 800 XE in 1989, computer club for kids in Prague, the programming accident in Java, studying and working for 16h a day, early interests in application servers, joining BEA Systems in 2003 and starting with version 6, the weblogic.jar and the weblogic "thin client" jar, the only BEA consultant in eastern Europe, Oracle's acquisition was a big change, leaving Oracle and moving to AVG for building custom application servers, starting at HomeCredit to develop with WebLogic, service buses and Co., joining a JavaONE conference session with Josh Long about SpringBoot, what is the purpose of FatJARs, one application per server, WebLogic became bigger over time, hollow JARs are explainable, about the costs of running application servers in the cloud, the deconstruction of the application server, how clustering became obsolete, application servers and docker layers, separation of business logic and infrastructure, the superfluous deployment machinery, the idea of a single application, the complicated application server's classloading, helidon only relies on the system ClassLoader, cloud features without clouds, starting at Oracle again, Airport, Prime, J4C and Helidon, helidon was fully opensourced in February, 2019, the origin Helidon idea was to be a cloud platform, Helidon's security is similar to WebLogic 8-9 security model, helidon separates between the user and service accounts, helidon's outbound security is automated, helidon was designed with docker in mind, helidon supports hollow jars and so directly the Docker layering, FatJARs are not worth the trouble, bare metal is the killer use case for FatJARs, hardcore classloaders are problematic with GraalVM, Helidon supports MicroProfile 3.0 all parts of it, merging all infrastructural modules in a single JAR is dangerous - beans.xml and class clashes are possible, helidon comes with JWT support fo outbound communication, in helidon you can provide you own main method, helidon comes with two modes: MicroProfile and Java SE, helidon is just a set of libraries, one library happens to be the server -- but is optional, helidon started as a Java SE platform only - microprofile came later, helidon was inspired by expressjs, trying to replicate the express experience, helidon ported the Java 9 flow API to Java 8 (by renaming the package) to backport the user experience, helidon uses the event loop of netty - never block the thread, most of Jakarta EE and Java SE libraries are not reactive, Java SE and MicroProfile modes can be used at the same time, helidon Java SE application is directly compilable with GraalVM to native image, Helidon 2.0 will come with native compilation support of MicroProfile, commercial support for Helidon will be probably possible, Helidon team answers questions on slack channel, no-one is interested in providing support of outdated software, MicroProfile is volatile - backward compatibility can be a challenge, Tomas Langer on twitter: @langer_tomas and on github: https://github.com/tomas-langer

DBs-ium, CDC and Streaming

An airhacks.fm conversation with Gunnar Morling (@gunnarmorling) about: The first Debezium commit, Randal Hauch, DBs-iuim, Java Content Repository JCR / modshape, exploring the Change Data Capture (CDC), how Debezium started, the MySQL binlog, the logical decoding in Postgres, Oracle Advanced Queuing, update triggers, Java Message System (JMS), there is no read detection, switching the current user at JDBC connection for audit purposes, helping Debezium with additional metadata table, using Kafka Streams to join the metadata and the payload, installing the logical decoding plugins into PostgreSQL, logical decoding plugin exposes the data from the write ahead log, decoding into protocol buffers with decoderbufs, in cloud environments like e.g. Amazon RDS you are not allowed to install any plugins, wal2json is verbose but comes preinstalled on RDS, pgoutput is responsible for the actual decoding of the events, debezium only sees committed transactions, debezium is mainly written in Java, decoderbufs was written by community and included to debezium, Debezium communicates with Postgres via the JDBC / Postgres API, pgoutput format is converted into Kafka Connector source format, Kafka Connect is a framework for running connectors, Kafka Connect comes with sink and source connectors, Kafka Connect comes with connector specific connectors like e.g. StringConverter, Converters are not Serializers, Debezium ships as Kafka Connect plugin, Kafka Connector runs as standalone process, running Debezium in embedded mode, JPA cache invalidation with Debezium, converting Debezium events into CDI events, converting database changes to WebSockets events, database polling vs the Debezium approach, DB2 will support Debezium, Oracle support is "on the horizon", Oracle LogmMiner, Oracle XStream, Debezium supports Microsoft SQL Server (starting with Enterprise license), Apache Pulsar comes with Debezium out-of-the-box, Pulsar IO, running Debezium as standalone service with outbounds APIs, MongoDB supports the "Debezium Change Event Format", Kafka Sink connectors are easy to implement, Debezium embedded mode and offsets, embedded connector has to remember the offset, an offset API is available for embedded Debezium connectors, combining CDC with Kafka Streams, Quarkus supports Kafka Streams and Reactive Messaging, Quarkus and Kafka Streams, Quarkus supports Kafka Streams in dev mode, replacing Hibernate Envers with Debezium, Messaging vs. Streaming or JMS vs. Kafka, Kafka is a database, the possible Debezium features, Cassandra support is coming, Outbox pattern is going to be better supported, transactional event grouping, dedicated topic for transaction demarcations, commercial support for Debezium, Debezium exposes JMX metrics, Five Advantages of Log-Based Change Data Capture, Reliable Microservices Data Exchange With the Outbox Pattern, Automating Cache Invalidation With Change Data Capture Gunnar Morling on twitter: @gunnarmorling and github: https://github.com/gunnarmorling.
