[infinispan-issues] [JBoss JIRA] Reopened: (ISPN-523) reduce Lucene Directory memory usage: store only initialized buffer ranges

reduce Lucene Directory memory usage: store only initialized buffer ranges -------------------------------------------------------------------------- Key: ISPN-523 URL: https://jira.jboss.org/browse/ISPN-523 Project: Infinispan Issue Type: Task Components: Lucene Directory Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 4.1.0.CR1, 5.0.0.BETA1 All buffers created prior to writing a new file chunk are initialized at bufferSize and then stored as-is (as the full buffer); In most cases the memory penalty due to unused areas is not noticeable as biggest files are split in several chunks, but the many smallest files containing metadata only are wasting more memory, as only a couple of bytes are used in each.
