Feature #21887

Updated by Peter Amstutz 5 months ago

Want to have estimates of storage usage. 

 Proposal: 

 Keep-balance keeps track of storage usage per-project, and updates the project records at the conclusion of each run, similarly to how it currently maintains the replication status fields for collections. 

 For each project, it should record: 

 * Perceived usage - approximately what you would get from sum(file_size_total) of collections in the project 
 * Project deduplicated usage - each unique block counted exactly once 
 * Whole cluster deduplicated usage - each unique block size multiplied by the ratio of (appearances of that block in project / appearances in whole cluster)
