Method Detail

setBalancerRan

public BalanceResponse.Builder setBalancerRan(boolean balancerRan)

Set true if the balancer ran, otherwise false. The balancer may not run in some circumstances, such as if a balance is already running or there are regions already in transition.

Parameters:

balancerRan - true if balancer ran, false otherwise

setMovesCalculated

public BalanceResponse.Builder setMovesCalculated(int movesCalculated)

Set how many moves were calculated by the balancer. This will be zero if the cluster is already balanced.

Parameters:

movesCalculated - moves calculated by the balance run

setMovesExecuted

public BalanceResponse.Builder setMovesExecuted(int movesExecuted)

Set how many of the calculated moves were actually executed by the balancer. This should be zero if the balancer is run with BalanceRequest.isDryRun(). It may also not equal movesCalculated if the balancer ran out of time while executing the moves.

Parameters:

movesExecuted - moves executed by the balance run

build

public BalanceResponse build()

Build the BalanceResponse
