--------------------------------------
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).
