         Key: DERBY-521
         URL: http://issues.apache.org/jira/browse/DERBY-521
     Project: Derby
        Type: Improvement
  Components: Store  
    Versions: 10.1.1.1    
    Reporter: Suresh Thalamati


During log file switch , the logging system blocks all the writes to the transaction log.
 One of the tasks during 
log switch  is preallocation.  By doing  preallocation  without blocking the log writes might
improve  throughput .
