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

             Summary: Warning if there are many Lucene documents
                 Key: OAK-6148
                 URL: https://issues.apache.org/jira/browse/OAK-6148
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: query
            Reporter: Thomas Mueller
             Fix For: 1.8


Lucene indexes are limited to Integer.MAX_VALUE (LUCENE-4104), so Lucene 
indexes can have at most around 2 billion nodes indexed.

We should avoid running into this limit. For example, we could log a warning if 
the number of documents is a multiple of 200 million, so a user has plenty of 
time to change the index configuration.

Also, it would be good to be able to read the current number of documents per 
index (using JMX for example), so that one can find out how far he is from the 
limit.
