Types

type QueryWatcher

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

QueryWatcher is a low-level, stateless watcher. Initial updates are sent in chunks. Once snapshot is complete, further changes are incremental - unless Reset flag is set, in which case another snapshot is received.

func NewQueryWatcher

func NewQueryWatcher(id int, client region_client.RegionServiceClient,
	params *QueryWatcherParams, evtsChan chan *QueryWatcherEvent) *QueryWatcher

func (*QueryWatcher) Run

func (qw *QueryWatcher) Run(ctx context.Context) error

type QueryWatcherEvent

type QueryWatcherEvent struct {
	Identifier   int
	Changes      []*region.RegionChange
	Reset        bool
	LostSync     bool
	InSync       bool
	SnapshotSize int64
	CheckSize    bool
}

type QueryWatcherParams

type QueryWatcherParams struct {
	Filter    *region.Filter
	View      view.View
	FieldMask *region.Region_FieldMask
	OrderBy   *region.OrderBy
	Cursor    *region.PagerCursor
	ChunkSize int
	PageSize  int
	WatchType watch_type.WatchType

	RecoveryDeadline time.Duration
	RetryTimeout     time.Duration
}

type Watcher

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

Watcher is higher level stateful watcher with dynamic + multi filter support.

func NewWatcher

type WatcherConfig struct {
	*gotenaccess.WatcherConfig

	// common params that must be shared across queries
	WatchType watch_type.WatchType
	View      view.View
	FieldMask *region.Region_FieldMask
	OrderBy   *region.OrderBy
	ChunkSize int
}
