[jira] [Commented] (SOLR-9844) Display fieldCache total size information

["Varun Thacker (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15740548#comment-15740548 ] 

Varun Thacker commented on SOLR-9844:
-------------------------------------

Also its annoying that the current entries show up like this

{code}
entry#0:              'org.apache.lucene.index.SegmentCoreReaders@​20836290'=>'cat',class org.apache.lucene.index.SortedDocValues,0.5=>org.apache.solr.uninverting.FieldCacheImpl$SortedDocValuesImpl#1504618891 (​size =~ 288 bytes)
{code}

I propose to simplify it to 

{code}
entry#0 field='cat' segment=_0 size='~288 bytes' 
{code}

So this will tell us the field , segment and size of the entry.

> We know the size of each entry in the fieldCache and display that on the admin UI screen under Plugin/Stats -> fieldCache currently.
> We also show the total entries count. Lets also show the total size of the cache . 
> This is valuable information to tell users how much heap memory is being occupied by the fieldCache.
