> For application like hbase WAL, it will be useful if application like hbase
> can give a hint to bk about application's preferred ledger location. In that
> way, application can fail over to specific machines where one of the ledger
> replica is located; the recovery time will be faster. Another scenario is
> hbase's support for hot standby region server where read request can be
> served from a different machine other than the active region server. That
> requires the hot standby region server to read from ledger. If the ledger is
> on the same machine as standby region server, the performance will be better.
