[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-153) Provide the possibility to configure writer.setRAMBufferSizeMB() (Lucene 2.3)

[ http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-153?pag... ] Sanne Grinovero commented on HSEARCH-153: ----------------------------------------- about "batchIndexParameters.setRamBufferSizeMB(64); " : I'm sure the Lucene team knows how to set good defaults for general use, what I'm suggesting is to set a default for the "batch" indexing mode; For non-batch indexing mode the RamBufferSize is less critical, as I expect it to never fill the default value before a forced flush(), but in batch mode it has a great impact on performance: the IndexWriter javadoc recommends setting it as high as possible, so I was thinking in proposing a bit higher default for batch mode; maybe 64MB could be dangerous for people not setting JVM heap parameters(or automated testings), so maybe it's not a good idea and it could be better to just recommend the user to set a high setting (already done in docs). What do you mean with "I am for a "default" value, open a different JIRA issue for it."? Should I open another issue to discuss appropriate default values? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
