Resolution: Won't Fix
Affects Version/s: 1.9, 2.0.0, 2.1
Fix Version/s: None
In response to this thread:
I think we should allow changing the compression level used in the call to java.util.zip.Deflator in FieldsWriter.java. Right now it's hardwired to "best":
Unfortunately, this can apparently cause the zip library to take a very long time (10 minutes for 4.5 MB in the above thread) and so people may want to change this setting.
One approach would be to read the default from a Java system property, but, it seems recently (pre 2.0 I think) there was an effort to not rely on Java System properties (many were removed).
A second approach would be to add static methods (and static class attr) to globally set the compression level?
A third method would be in document.Field class, eg a setCompressLevel/getCompressLevel? But then every time a document is created with this field you'd have to call setCompressLevel since Lucene doesn't have a global Field schema (like Solr).
Any other ideas / prefererences for either of these methods?
