Hello,
I am sorry for the delay.
Not sure what you mean by "workload". We have a performance tests, which
started failing after upgrading to 8.7.0.
So I just tried to query the index (built form the same source) to get all
documents and compare the performance with 7.5.0.
Document "size" is a sum of all stored string lengths (3402519 documents):
doc size 903 - 88s vs 22s
doc size 36 (only one field loaded, used searcher.doc(docID,
Collections.singleton("fieldName"))) - 78s vs 16s
doc size 439 (some fields made not stored) - 46s vs 14.5s
Best regards,
Martynas
