Hello,
We were investigating one HEAP DUMP in which FielsCaceImpl has occupied around
5GB. Upon further investigation, I got to know that
FieldCacheImpl$SortedDocValues occupies 90% of the memory where
FieldCacheImpl$CacheKey is "id".
When I checked the logs I was trying to find any query in which there is any
sort on id field. But instead I find few queries in which we are sorting on
_docid_ lucene internal id.
Can sort on _docid_ cause OOM?
And if I will enable docValues for uniqueKey(id) will that solve my problem?
