Problem
-------
Metric Metadata is not retained properly when a gauge is constructed via CumulativeGauge's addGauge method.

Solution
--------
Remove the optimization that was leading to the lost MetricMetadata. The optimization was to avoid creating a new function on each call to whenGaugeNotPresent by having functions for each of the Verbosity levels. Now, there is more Metadata to store than simply Verbosity and we cannot have a cached function for all possible Metadata values.

Result
------
Metric Metadata is now properly populated and retained when CumulativeGauge's addGauge method.

Finagle

Build status Codecov Project status Gitter Maven Central

Status

This project is used in production at Twitter (and many other organizations), and is being actively developed and maintained.

Releases

Releases are done on an approximately monthly schedule. While semver is not followed, the changelogs are detailed and include sections on public API breaks and changes in runtime behavior.

Getting involved

Finagle is an extensible RPC system for the JVM, used to construct high-concurrency servers. Finagle implements uniform client and server APIs for several protocols, and is designed for high performance and concurrency. Most of Finagle’s code is protocol agnostic, simplifying the implementation of new protocols.

For extensive documentation, please see the user guide and API documentation websites. Documentation improvements are always welcome, so please send patches our way.
