so it’s a JIRA for sure. I’ve seen indexes with 100s of segments. With a large
synonym file it’d be terrible.
I would be really, really, really surprised if this is the case. The Lucene
people are very careful with me
That sounds really strange to me.
Segments are created gradually depending on changes applied to the
index, while the Schema should have a completely different lifecycle,
independent from that.
If that is true, that would mean each time a new segment is created Solr
would instantiate a new Sche
Yes, I think so.
While integrating a Thesaurus as synonyms.txt I saw massive memory usage.
A heap dump and analysis with MemoryAnalyzer pointed out that the
SynonymMap took 3 times a huge amount of memory, together with each
opened index segment.
Just try it and check that by yourself with heap du
mmm, ok for the core but are you sure things in this case are working
per-segment? I would expect a FilterFactory instance per index,
initialized at schema loading time.

Hi,
looking at the stateful nature of SynonymGraphFilter/FilterFactory classes,
the answer should be 2 times (one time per type instance).
The SynonymMap, which internally holds the synonyms table, is a private
member of the filter factory and it is loaded each time the factory needs
to create a t
