PeterOeClausen opened a new issue, #784:
URL: https://github.com/apache/lucenenet/issues/784
I'm running the latest Lucene .NET versions:
Lucene.Net 4.8.0-beta00016
Lucene.Net.Analysis.Common 4.8.0-beta00016
I'm doing the following:
```cs
using var analyzer = new KeywordAnalyzer();
using var directory = FSDirectory.Open(IndexPath);
var config = new IndexWriterConfig(LuceneVersion, analyzer)
{
OpenMode = OpenMode.CREATE, // Use OpenMode.CREATE to
overwrite, or OpenMode.APPEND to just open
RAMPerThreadHardLimitMB = 100,
RAMBufferSizeMB = 100,
};
using var writer = new IndexWriter(directory, config);
// Write index to disk
writer.AddDocuments(productDocuments);
writer.AddDocuments(productCategoryDocuments);
writer.AddDocuments(productTypeDocuments);
writer.AddDocuments(productLineDocuments);
writer.Commit();
```
As soon as writer.AddDocuments() is called, the memory consumption grows a
lot.
You can see the sudden increase in the Diagnostic Tool in visual studio:
Running it multiple times keeps increasing the memory usage up to 3GB, at
which point it doesn't grow any longer. And these 3GB are never released again.
The program doesn't crash, and it stops acquiring memory.
I want to limit how much memory Lucene can use, but using `RAMBufferSizeMB`
and `RAMPerThreadHardLimitMB` seems to have no effect at all.
I tried flushing as well, which had no effect, and I tried calling Dispose()
which also had no effect.
I've also tried setting MaxBufferedDocs to 1000, still no limit to RAM usage.
Have I missed something in the documentation? Is there a way to limit RAM
usage of the Lucene .NET IndexWriter?
