On behalf of the Spring and Apache Geode communities, it is my pleasure to announce the release of Spring Boot for Apache Geode & Pivotal GemFire (SBDG)
1.1.0.RELEASE and the
Spring Boot for Apache Geode & Pivotal GemFire (SBDG)
1.2.0.M1 was a baseline release to align SBDG on latest GemFire/Geode and Spring bits:
Spring Framework 5.2.0.RC1
Spring Boot 2.2.0.M5
Spring Data Moore-RC2/2.2.0.RC2
Spring Session Corn-M3/2.2.0.M3
With Spring Data Moore, this additionally pulls in:
Apache Geode 1.9.0
Pivotal GemFire 9.8.3
Spring Boot for Apache Geode & Pivotal GemFire (SBDG)
1.1 covered a lot of ground. In this release line we included many important changes and features to help developers stay productive and solve important and relevant problems.
Let’s have a look back at a few highlights and worthy mentions.
1.1 is based on:
Spring Framework 5.1.9.RELEASE
Spring Boot 2.1.7.RELEASE
Spring Data Lovelace-SR10/2.1.10.RELEASE
Spring Session Bean-SR7/2.1.7.RELEASE
With Spring Data Lovelace, this pulls in:
Apache Geode 1.6.0
Pivotal GemFire 9.5.4
Support for Caching Use Cases & Patterns
It’s hard to argue that with the proliferation of Microservices in a Cloud context, caching will be 1 of the most common and important patterns used for Cloud-Native development.
No longer is caching only needed to improve on performance when accessing data from a relational database. Caching will be increasingly common and critical when a Microservice becomes the new data source by which your application accesses information.
This is because networks are inherently prone to failures and incur a significant latency penalty anytime a network-hop happens. This can prove to be fatal for applications under intense load, leading to all sorts of cascading failures (e.g. memory problems). The goal is to minimize the unnecessary network calls as much as possible, which is quite easy to do especially when the proportion of reads far exceeds writes.
Caching (HTTP) Session state will continue to be the most common form of caching. Fortunately, the awesome power of
Spring Session, and in particular
Spring Session for Apache Geode & Pivotal GemFire, to manage your Spring Boot application’s Session state, for all types of Sessions (HTTP, WebSockets and WebSessions (Reactive)) is really simple. Plus,
Spring Session, with its support for a wide variety of backing stores (JDBC, Redis, MongoDB, Hazelcast, and of course, GemFire/Geode) makes it stupid simple to switch providers if/when your requirements change.
Hybrid Cloud Deployments
1.1, you can now deploy your Spring Boot applications to
Pivotal CloudFoundry (PCF), yet still connect those apps to external data sources.
Hybrid Cloud arrangements are common when data must be protected and kept on-prem. It is also a very common intermediate step for companies trying to migrate to the cloud and modernize their stack. Hybrid deployments enable companies to take an incremental approach to cloud adoption as opposed to an all or nothing approach.
Therefore SBDG includes
first-class support for running your Spring Boot applications in PCF, yet connect those apps to externally managed, standalone Apache Geode or Pivotal GemFire clusters.
On a related note, in addition to Hybrid Cloud Deployments, SBDG additionally supports:
Making the Switch
1.1 (even before 1.1), has been focused on developer productivity: helping users get up and running as easily and quickly and reliably as possible!
Part of the strategy is rooted in helping users and customers:
In fact, it is equally important that you can move both ways. From Managed back to Standalone environments and from Commercial back to Open Source. Again, it should just work!
That is what the
switch is all about… "choice", and specifically, "your" choice.
Many More Changes
Along with the changes mentioned above, there were several other changes that went into SBDG
1.1 as well. See the
changelog for complete details.
All focus now shifts to SBDG
1.2. There are several areas we will continue to invest in.
What does this mean technically?
We are planning to introduce a new annotation,
@EnableClusterAware, that when declared along with your
@SpringBootApplication class, will enable you to move from a local development context (e.g. your IDE) to client/server without needing to worry about connections details and configuration of your cluster. SBDG will figure it out for you! This will make "switching" between environments (e.g. DEV & TEST/STAGING) even easier, especially as you are quickly iterating in development when debugging and testing your code.
Additionally, we will enable developers in a PCF context to assign users with specific roles to their deployed Spring Boot applications when running the app. This is important for certain UCs where the application must be ran in read-only mode, where the app can only read data, but not modify it.
To compliment the Look-Aside, Inline and Near Caching Patterns, we will provide another Guide along with Example Code showcasing the power of Multi-Site, WAN topologies as applied to caching, and how this helps further increase the availability and resilience of your application architecture (think Active-Active, Active-Passive , Availability Zones, etc).
1.2 bits are making their way to
start.spring.io. In the near future, you will be able to select Apache Geode as an option when developing Spring Boot applications, which will conveniently provide you with the
All this and much more to come.
As always your continued feedback is highly appreciated and welcomed. It is your contributions that make SBDG a valuable project. Thank you.
P.S. Don’t miss your opportunity to learn from the very best at this year’s
SpringOne Platform 2019 in Austin, TX from October 7th to the 10th. Looking forward to seeing all of you there!
