Validate check job config should be valid

Types

type EnumMutator

type EnumMutator interface {
	EnumReader
	// ExtendEnumCases try to extend new enum cases to given column
	ExtendEnumCases(namespace, table, column string, enumCases []string) ([]int, error)
}

EnumMutator defines EnumMutator interface

type EnumReader

type EnumReader interface {
	// GetEnumCases get all enum cases for the given table column
	GetEnumCases(namespace, table, column string) ([]string, error)
}

EnumReader reads enum cases

type IngestionAssignmentMutator

type IngestionAssignmentMutator interface {
	GetIngestionAssignment(namespace, name string) (IngestionAssignment models.IngestionAssignment, err error)
	GetIngestionAssignments(namespace string) (IngestionAssignment []models.IngestionAssignment, err error)
	DeleteIngestionAssignment(namespace, name string) error
	UpdateIngestionAssignment(namespace string, IngestionAssignment models.IngestionAssignment) error
	AddIngestionAssignment(namespace string, IngestionAssignment models.IngestionAssignment) error
	GetHash(namespace, subscriber string) (string, error)
}

IngestionAssignmentMutator defines rw operations

type JobMutator

type JobMutator interface {
	GetJob(namespace, name string) (job models.JobConfig, err error)
	GetJobs(namespace string) (job []models.JobConfig, err error)
	DeleteJob(namespace, name string) error
	UpdateJob(namespace string, job models.JobConfig) error
	AddJob(namespace string, job models.JobConfig) error
	GetHash(namespace string) (string, error)
}

JobMutator defines rw operations

type MembershipMutator

type MembershipMutator interface {
	// Join registers an instance to a namespace
	Join(namespace string, instance models.Instance) error
	// GetInstance returns an instance
	GetInstance(namespace, instanceName string) (models.Instance, error)
	// GetInstances returns a list of instances in a namespace
	GetInstances(namespace string) ([]models.Instance, error)
	// Leave removes an instance
	Leave(namespace, instanceName string) error
	// GetHash returns hash of all instances
	GetHash(namespace string) (string, error)
}

MembershipMutator defines membership rw operations

type NamespaceMutator

type NamespaceMutator interface {
	CreateNamespace(namespace string) error
	ListNamespaces() ([]string, error)
}

NamespaceMutator mutates table metadata

type NotExist

type NotExist string

NotExist represents not exist error

func (NotExist) Error

func (e NotExist) Error() string

type SubscriberMutator

type SubscriberMutator interface {
	// GetSubscriber returns a subscriber
	GetSubscriber(namespace, subscriberName string) (models.Subscriber, error)
	// GetSubscribers returns a list of subscribers
	GetSubscribers(namespace string) ([]models.Subscriber, error)
	// GetHash returns hash of all subscribers
	GetHash(namespace string) (string, error)
}

SubscriberMutator defines rw operations only read ops needed for now, creating and removing subscriber should be done by each subscriber process

type TableSchemaMutator

type TableSchemaMutator interface {
	ListTables(namespace string) ([]string, error)
	GetTable(namespace, name string) (*common.Table, error)
	CreateTable(namespace string, table *common.Table, force bool) error
