[Hawkular-dev] Hawkular Metrics 0.12.0 - Release

[Stefan Negrea]

Hello Everybody,

I am happy to announce release 0.12.0 of Hawkular Metrics. This release is anchored by Hawkular integration enhancements, under-the-cover refactoring and changes in code structure, and removal of the deprecated JAX-RS 1.1 implementation.



Here is a list of major changes in this release:

1) Hawkular Authentication
  * When deployed part of Hawkular distribution, Hawkular Metrics uses Hawkular Accounts for authentication and authorization
  * Due to multi-tenant data segregation, Hawkular Accounts does both authentication and authorization since there are no specific permissions within Hawkular Metrics
  * For more details: HWKMETRICS-69, HWKMETRICS-344

2) Performance Improvements
  * Removed obsolete code for tracking tenants; this increased for cases where data was written under a tenant that did not exist before (HWKMETRICS-341)
  * Removed the virtual clock handler (used to accelerate internal metrics clock) since it is no longer used (HWKMETRICS-340)

3) JAX-RS 1.1 Implementation - Removed
  * The already deprecated JAX-RS 1.1 implementation of Hawkular Metrics has now been removed from the source tree and the modules consolidated
  * Going forward only JAX-RS 2.0 implementation of the REST API is available

4) Wildfly 10 - Deploying & Running
  * Deploying and running the project on Wildfly 10 is now fully supported
  * IMPORTANT: Support for Wildfly 9 is now dropped
