Subject [jira] [Created] (COUCHDB-2001) Finish the size calculating changes
Date Sun, 15 Dec 2013 17:33:07 GMT
Volker Mische created COUCHDB-2001:
--------------------------------------

             Summary: Finish the size calculating changes 
                 Key: COUCHDB-2001
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2001
             Project: CouchDB
          Issue Type: Improvement
          Components: BigCouch
            Reporter: Volker Mische


The #leaf{} record change is to enable us to add more data size
calculations. CouchDB master calculates a data size that account for
all bytes that are active in a .couch file. Cloudant is interested in
the total size of uncompressed docs and attachments minus the internal
overhead of btrees. And there’s a fourth number to calculate based on
the compression level used. Having each of these numbers will be
useful as well as the calculations they’ll enable (ie, dead bytes in
file, bytes used for overhead, compression ratio achieved, etc).
