Specified by:

run in class RaftOp

Parameters:

groupId - groupId of the specific Raft group

commitIndex - commitIndex of the log entry keeping this operation

Returns:

result of the operation execution

isRetryableOnIndeterminateOperationState

public boolean isRetryableOnIndeterminateOperationState()

Description copied from interface: IndeterminateOperationStateAware

Returns true if duplicate commit of the operation is equivalent to committing it only once.

Specified by:

isRetryableOnIndeterminateOperationState in interface IndeterminateOperationStateAware

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID
