Hi Spring fans! Welcome to another installment of This Week in Spring! This week I'm in blizzard-besieged Boston, Massachusetts, for the epic Spring One Tour Boston event. Unfortunately, due to this crazy snow storm / blizzard, the event's been postponed one day as we all grapple with the weather. Hope you were able to join the Spring Boot 2.0 launch webinar! If not the replay will be available here and don't forget to check out the launch blog!

Snow or no snow! The show must go on, at least here on the Spring blog, so without further ado:

• The Reactor team is looking for a motivated new engineer to join the team - apply now!
• Spring Cloud Data Flow ninja Gunnar Hillert has just announced Spring Cloud Data Flow 1.4 RC1

• The Spring Data JDBC project has added @Modify for marking queries that perform DML or DDL. Modifying queries will return type boolean or Boolean when the number of updated rows is greater 0. This shouldn't be used for DML statements since it will always return false.
• Spring Web Flow lead Rossen Stoyanchev has just announced Spring Web Flow 2.5. This release provides an upgrade path for applications using Web Flow to Spring Framework 5 with Java 8, Servlet 3.1, Hibernate 5, Tiles 3, and JSF 2.2 as minimum requirements.
• Spring Boot legend Madhura Bhave looks at support for testing auto-configurations in Spring Boot 2.0

• This thread is a nice breakdown on some ways to approach error handling using Project Reactor, as in a Spring WebFlux application.
• This is an interesting post that looks at a particular way to quantify how responsive a system is - Apdex. It's yet another useful application of a time series DB (like Prometheus, Graphite, InfluxDB, etc.) and you're going to need a metrics facade like Micrometer to use it.
• RxJava 2 lead and frequent Pivotal Reactor contributor David Karnok has a nice benchmark of RxJava and Reactor
