Caching is a common component in almost every production application. This SDK provides a consistent interface, CacheService, and implementations that decorate different underlying implementations (NoOpCacheService, InMemoryCacheService, MemcachedCacheService , RedisCacheService and RedisCacheServiceAsBytes).

This allows caching to be implemented in the most common use cases concisely:

RedisCacheService.initialise(clusterEndPointIP, clusterPort, shutdownMonitor);
CachService service = RedisCacheService.getInstance();

service.trySaveItemToCache(...
// and
service.tryGetCachedItem(...

Using CacheService we also provide a CacheCheckPeriodic utility that allows a cached value to be checked periodically, using an in memory result otherwise. This allows for high performance feature-flags.

For our latest stable release use:

We use semantic versioning.

All merges into DEV will automatically get released as a maven central snapshot, which can be easily included in any downstream dependencies that always desire the latest changes (see above for 'Most Up To Date' installation).

Each merge into the MASTER branch will automatically get released to Maven central and github releases, using the current library version. As such, following every merge to master, the version number of the dev branch should be incremented and will represent 'Work In Progress' towards the next release.

Please use a merge (not rebase) commit when merging dev into master to perform the release.

To create a full release to Maven central please follow these steps:

1. Ensure the CHANGELOG.md is up to date with all the changes in the release, if not please raise a suitable PR into DEV. Typically the change log should be updated as we go.
2. Create a PR from DEV into MASTER. Ensure the version in the pom.xml is the correct version to be released. Merging this PR into MASTER will automatically create the maven and github releases. Please note that a release is final, it can not be undone/deleted/overwritten.
3. Once the public release has been successful create a final PR into DEV that contains an incremented pom.xml version to ensure the correct snapshot gets updated on subsequent merges into DEV. This PR should also include:
   • An update to the README.md latest stable release version number.
   • A 'Work In Progress' entry for the next anticipated release in CHANGELOG.md.
