Constants

const (
	// LogicalInitialType declares a job type for preparing a logical initial snapshot.
	LogicalInitialType = "logicalSnapshot"
)

const (
	// PhysicalInitialType declares a job type for preparing a physical snapshot.
	PhysicalInitialType = "physicalSnapshot"

Types

type DataPatching

type DataPatching struct {
	DockerImage        string             `yaml:"dockerImage"`
	QueryPreprocessing QueryPreprocessing `yaml:"queryPreprocessing"`
}

DataPatching allows executing queries to transform data before snapshot taking.

type HealthCheck

type HealthCheck struct {
	Interval   int64 `yaml:"interval"`
	MaxRetries int   `yaml:"maxRetries"`
}

HealthCheck describes health check options of a promotion.

type LogicalInitial

type LogicalInitial struct {
	// contains filtered or unexported fields
}

LogicalInitial describes a job for preparing a logical initial snapshot.

func NewLogicalInitialJob

func NewLogicalInitialJob(cfg config.JobConfig, global *global.Config, cloneManager pool.FSManager) (*LogicalInitial, error)

NewLogicalInitialJob creates a new logical initial job.

func (*LogicalInitial) Name

func (s *LogicalInitial) Name() string

Name returns a name of the job.

func (*LogicalInitial) Reload

func (s *LogicalInitial) Reload(cfg map[string]interface{}) (err error)

Reload reloads job configuration.

func (*LogicalInitial) Run

func (s *LogicalInitial) Run(ctx context.Context) error

Run starts the job.

type LogicalOptions

type LogicalOptions struct {
	DataPatching        DataPatching      `yaml:"dataPatching"`
	PreprocessingScript string            `yaml:"preprocessingScript"`
	Configs             map[string]string `yaml:"configs"`
	Schedule            Scheduler         `yaml:"schedule"`
}

LogicalOptions describes options for a logical initialization job.

type PhysicalInitial

type PhysicalInitial struct {
	// contains filtered or unexported fields
}

PhysicalInitial describes a job for preparing a physical initial snapshot.

func NewPhysicalInitialJob

func NewPhysicalInitialJob(cfg config.JobConfig, global *global.Config, cloneManager pool.FSManager) (*PhysicalInitial, error)

NewPhysicalInitialJob creates a new physical initial job.

func (*PhysicalInitial) Name

func (p *PhysicalInitial) Name() string

Name returns a name of the job.

func (*PhysicalInitial) Reload

func (p *PhysicalInitial) Reload(cfg map[string]interface{}) (err error)

Reload reloads job configuration.

func (*PhysicalInitial) Run

func (p *PhysicalInitial) Run(ctx context.Context) (err error)

Run starts the job.

type PhysicalOptions

type PhysicalOptions struct {
	SkipStartSnapshot   bool              `yaml:"skipStartSnapshot"`
	Promotion           Promotion         `yaml:"promotion"`
	PreprocessingScript string            `yaml:"preprocessingScript"`

}

PhysicalOptions describes options for a physical initialization job.

type Promotion

type Promotion struct {
	Enabled            bool               `yaml:"enabled"`
	DockerImage        string             `yaml:"dockerImage"`
	HealthCheck        HealthCheck        `yaml:"healthCheck"`
	QueryPreprocessing QueryPreprocessing `yaml:"queryPreprocessing"`
	Configs            map[string]string  `yaml:"configs"`
	Recovery           map[string]string  `yaml:"recovery"`
}

Promotion describes promotion options.

type QueryPreprocessing

type QueryPreprocessing struct {
	QueryPath          string `yaml:"queryPath"`
	MaxParallelWorkers int    `yaml:"maxParallelWorkers"`
}

QueryPreprocessing defines query preprocessing options.
