-------------------------------------
Summary: Add support for new Oracle ZGC garbage collector
Key: GEODE-7483
URL: https://issues.apache.org/jira/browse/GEODE-7483
Project: Geode
Issue Type: Improvement
Components: client/server
Reporter: Alex Dubrouski
Good afternoon,
We have a POC Geode cluster and few regions have pretty short TTLs for keys,
thus sometimes we experience spikes in garbage collection pauses due to
eviction of large amount of weak references. I tried to switch cluster to
Oracle new ZGC (it supposed to process weak roots concurrently, so
theoretically there will be trade off long pauses for CPU usage spikes), but I
am getting this error when starting a server:
{code:java}
[error 2019/11/20 13:01:58.302 PST <main> tid=0x1] No tenured pools found.
Known pools are: [(Name=CodeHeap 'non-nmethods';Type=Non-heap
memory;UsageThresholdSupported=true), (Name=Metaspace;Type=Non-heap
memory;UsageThresholdSupported=true), (Name=ZHeap;Type=Heap
memory;UsageThresholdSupported=true), (Name=CodeHeap 'profiled
nmethods';Type=Non-heap memory;UsageThresholdSupported=true), (Name=CodeHeap
'non-profiled nmethods';Type=Non-heap memory;UsageThresholdSupported=true)]
{code}
(OpenJDK v13.0.1)
Could you please implement support for new generation of low pause garbage
collectors?
Thanks.
Regards,
Alex Dubrouski
