Owen Nichols closed GEODE-9800. ------------------------------- > improve radish info maxmemory and used_memory > --------------------------------------------- > > Key: GEODE-9800 > URL: https://issues.apache.org/jira/browse/GEODE-9800 > Project: Geode > Issue Type: Improvement > Components: redis > Affects Versions: 1.15.0 > Reporter: Darrel Schneider > Assignee: Jens Deppe > Priority: Major > Fix For: 1.15.0 > > > Currently the radish INFO command returns values for maxmemory and > used_memory that are not as helpful as they could be. > For maxmemory it returns PartitionedRegion.getLocalMaxMemory. That is just a > hint to geode to help it decide which server should get a new bucket. It in > no ways limits how much data can be stored in the region. But radish also > stores things in the server that do not go in a region (pubsub info). So > maxmemory should instead be equal to java.lang.Runtime.maxMemory(). > For used_memory it return dataStore.currentAllocatedMemory(). But that only > shows how much data is stored in the region locally (and is only an estimate > of that) so once again does not account for pubsub or for all the extra > overhead we have in our radish implementation. So instead it should return > Runtime.maxMemory()-Runtime.freeMemory(). Note that Runtime.totalMemory() > should not be used since some jvms set totalMemory to maxMemory. Even when > that is done freeMemory() has a meaningful value so max-free is a good > estimate of "used_memory". -- This message was sent by Atlassian Jira (v8.20.7#820007)
