Hi Guys, I have been finding out the heap space requirement for indexing and searching with 3.0.2 vs 4.1 (with BlockPostings Format).
I have a 2GB index with 1 million docs with around 42 fields with 40 fields being random strings. I have seen that memory for search has reduced by 5X with 4.1 (with BlockPostings Format) but the memory usage during indexing with 4.1 is around 800MB~1.7 GB whereas for 3.0.2 it is 300~600MB. But indexing time is almost same with both versions. So, 2~3X more memory required for 4.1 version for indexing. What could be the reasons for this ? Did i go wrong somewhere ? Can somebody explain ?
