> In our environment, in Salesforce, we are likely to have bookie nodes with
> different storage capacity: some will have 1TB others might have 3TB. 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.
