JVM Heap usage didn't decline after clearing field data cache by clear cache API


(Gary Gao) #1

Hi,
While I cleared field data cache using Clear Cache API:
$curl -XPOST
'http://localhost:9200/_cache/clear?field_data=true'
field data cahced size decreased, indeed, but JVM heap usage didn't
declined.
What's the reasons ?
