The changes have two advantages: > * Decoupling the namespace and the block management layer. It is a > prerequisite step to move block management off the heap or to a separate > process. > * Increased flexibility on replicating blocks. Currently the replication > factors of all blocks have to be the same. The replication factors of these > blocks are equal to the highest replication factor across all snapshots. The > changes will allow blocks in a file to have different replication factor, > potentially saving some space. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
