Hi David
If you use lazy field loading (/enableLazyFieldLoading=true/)
/documentCache/ functionality is somehow limited. This means that the
document stored in the /documentCache/ will contain only those fields
that were passed to the /fl /parameter.
/documentCache/ requires memory, the more memory, the more field you
stored in the index, so if you have many stored field then documentCache
requires much memory.
Best regards

Hello,
we have a Solr Cloud 4.7, but this question is also related with other
versions, because we have tested this in several installations.
We have a very big index ( more than 400K docs) with big documents, but
in our queries we don't fetch the large fields in fl parameter. But, we
have seen that memory grows when we look for big documents because of the
Document Cache. This only happens in some queries we have to do, with
maybe more than 1000 docs in the response. We have set
enableLazyFieldLoading to true, so, we think that Document Cache should
grow more or less the same with all documents because we only fetch ID
field.
My question is: What does Solr exactly do when enableLazyFieldLoading is
set to true? Why does the size of the document have an influence in the
memory consumption?
Thanks in advance,
