What’s New
-
Zing 22.12.0.0, through various changed and updates, has been able to achieve 10% lower GC CPU usage on Cassandra.
-
Zing 22.12.0.0 lowers the amount of GC pauses with hidden classes.
-
Falcon has been improved for Jackson as well as other optimizations to the Falcon JIT compiler.
-
New JMX MXBean metrics replace old metric name below java.lang.GarbageCollector to increase accuracy for GC monitoring added with JDK-8265136: Previously, metric "GPGC New/Old" was providing a sum of GC pauses and concurrent GC duration. This metric is replaced by the following:
-
GPGC New/Old Cycles: duration time in ms of the concurrent GC which runs in parallel to application threads and is not stopping the application.
-
GPGC New/Old Pauses: GC pause time in ms.
-
On Java 11 and 17, the new metrics are enabled by default and the old removed. If you need to switch back to the old metric, add -XX:+GPGCReportLegacyGarbageCollectorMXBean.
On Java 8, only the old metric is active by default. To switch to the new metric add -XX:-GPGCReportLegacyGarbageCollectorMXBean.
