Comment 1 JBoss JIRA Server 2013-11-07 18:15:14 UTC

Steven Hawkins <shawkins> made a comment on jira TEIID-2714

added org.teiid.compactBufferFiles system property to the admin guide to keep more compact buffer file, defaults to false.  This could be tweaked further as the defrag/truncate cycle is initiated after 2^14 block removals.  Given that a typical allocation is around 64k this should reclaim space after a turn over of several hundred megs to a gig (note that we'll be somewhat compact already since we assign blocks from the start of the files).

Assuming this will be set to VERIFIED before GA - setting requires_doc_text- accordingly.

Comment 3 wgibson 2014-02-11 17:51:12 UTC

Covered by unit tests:  TestBufferFrontedFileStoreCache.java, TestFileStorageManager.java, and TestEnginePerformance.java.
