Hi
Using SolrCloud I have added the following to solrconfig.xml (actually
the node in zookeeper)
<ramBufferSizeMB>512</ramBufferSizeMB>
After that I expected that my Lucene index segment files would be a bit
bigger than 1KB as I'm indexing very small documents
Enabling the infoStream I see a lot of "flush at getReader" (one segment
of the infoStream file pasted below)
1. Where can I look for why documents are flushed so frequently?
2. Does it have anything to do with "getReader" and can I do anything so
Solr doesn't need to get a new reader so often?
Any comments are most welcome.
Best regards Trym
