Functions

func Validate 

func Validate(p Placement) error

Validate validates a placement to ensure: - The shards on each instance are in valid state. - The total number of shards match rf * num_shards_per_replica. - Each shard shows up rf times. - There is one Initializing shard for each Leaving shard. - The instances with same shard_set_id owns the same shards.
