Hi,
I am using Lucene 2.9.4 with FSDirectory.
My index has 80 thousand documents (each document has 12 fields).
My jvm has 70Mb of RAM memory (limited by my hosting).
I am getting various OutOfMemoryError.
I ran jmap and I got:
num #instances #bytes Class description
--------------------------------------------------------------------------
1: 275926 32074080 char[]
2: 657724 31570752
org.apache.lucene.index.FreqProxTermsWriter$PostingList
3: 200 16094896 org.apache.lucene.index.RawPostingList[]
The Lucene is consuming 47Mb of RAM memory.
Why there is this excessive memory consumption in FSDirectory?
Is it correct? I'm using FSDirectory because I haven´t a big amount of
RAM memory.
Thanks.
