func (f *CommandFactory) CreateCompareAndSwapCommand(key string, value string, prevValue string, prevIndex uint64, expireTime time.Time) raft.Command

CreateCompareAndSwapCommand creates a version 2 command to conditionally set a key in the store.

func (*CommandFactory) CreateCreateCommand

func (f *CommandFactory) CreateCreateCommand(key string, dir bool, value string, expireTime time.Time, unique bool) raft.Command

CreateCreateCommand creates a version 2 command to create a new key in the store.

func (*CommandFactory) CreateDeleteCommand

func (f *CommandFactory) CreateDeleteCommand(key string, dir, recursive bool) raft.Command

CreateDeleteCommand creates a version 2 command to delete a key from the store.

func (*CommandFactory) CreateSetCommand

func (f *CommandFactory) CreateSetCommand(key string, dir bool, value string, expireTime time.Time) raft.Command

CreateSetCommand creates a version 2 command to set a key to a given value in the store.

func (*CommandFactory) CreateSyncCommand

func (f *CommandFactory) CreateSyncCommand(now time.Time) raft.Command

func (*CommandFactory) CreateUpdateCommand

func (f *CommandFactory) CreateUpdateCommand(key string, value string, expireTime time.Time) raft.Command

CreateUpdateCommand creates a version 2 command to update a key to a given value in the store.

func (*CommandFactory) CreateUpgradeCommand

func (f *CommandFactory) CreateUpgradeCommand() raft.Command

CreateUpgradeCommand is a no-op since version 2 is the first version to support store versioning.
