4.3.0.RC2

Changes between 4.2.2 and 4.3.0.RC2

This is a release candidate for 4.3.0, a maintenance release that includes 2 new features and bug fix. This release is backward-compatible with 4.2.2.

Support Micrometer

The Java Client supports Micrometer through its MicrometerMetricsCollector implementation of MetricsCollector. Micrometer is an instrumentation facade, which supports popular metrics backends (Atlas, Graphite, Ganglia, Datadog, JMX, etc). Note Micrometer requires Java 8 or more. The Java Client 4.3.x still supports Java 6, but Micrometer support isn't usable on Java 6 and Java 7.

Make auto-recovery retry interval calculation pluggable

The RecoveryDelayHandler interface has been introduced to calculate the retry interval between each connection recovery attempt. The default strategy is still the same: a constant interval (5 seconds by default). The ExponentialBackoffDelayHandler implementation can be used to have an exponential retry interval.
