----------------------------------

             Summary: If there are always readers active, the commit queue 
can't be flushed.
                 Key: JENA-703
                 URL: https://issues.apache.org/jira/browse/JENA-703
             Project: Apache Jena
          Issue Type: Improvement
          Components: TDB
    Affects Versions: Jena 2.11.1
            Reporter: Andy Seaborne


The commit queue can only be flushed when the main storage is quiet.  A stream 
of readers can lead to the main storage never being quiet.

One possibility is to place a maximum (quite high) on the number of readers 
allowed after the decision to flush the journal to main storage. If exceeded,  
then lock readers for a while, flush and resume.
