[jira] [Created] (LUCENE-4531) Does CompressingStoredFieldsFormat only support less than 2G segment, thanks.

Littlestar created LUCENE-4531:
----------------------------------

             Summary: Does CompressingStoredFieldsFormat only support less than 2G segment, thanks.
                 Key: LUCENE-4531
                 URL: https://issues.apache.org/jira/browse/LUCENE-4531
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/codecs
    Affects Versions: 4.1
         Environment: Centos
            Reporter: Littlestar
            Priority: Minor


I see a note on CompressingStoredFieldsFormat.java.
>>>>
For a chunk size of chunkSize bytes, this StoredFieldsFormat does not support documents larger than (2^31 - chunkSize) bytes. In case this is a problem, you should use another format, such as Lucene40StoredFieldsFormat.
>>>>
Does CompressingStoredFieldsFormat only support less than 2G segment?
Is this a bug?

Adrien Grand commented on LUCENE-4531:
--------------------------------------

Hi Littlestar, ~2GB is the maximum size of one single document. Segments can grow much larger (for example we have a test that creates more than 4GB of stored fields).
