Also, > our ledgers are likely going to be long lived. The current ledger placement > policy selects the bookies randomly leading to uniform distribution. This > would cause some of bookies to reach high utilization while the rest would be > underutilized. We need a new ledger placement policy that has higher > probability of selecting bookies with higher free disk space than the ones > with lower disk free space. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
