Types

type NormalPartition 

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

NormalPartition is used to distribute load of a TaskQueue in multiple Matching instances. A normal partition is identified by `partitionId`. The partition with ID 0 is called a root partition.

func MustNormalPartitionFromRpcName added in v1.25.0 

func MustNormalPartitionFromRpcName(rpcName string, namespaceId string, taskType enumspb.TaskQueueType) *NormalPartition

func NormalPartitionFromRpcName 

func NormalPartitionFromRpcName(rpcName string, namespaceId string, taskType enumspb.TaskQueueType) (*NormalPartition, error)

func (*NormalPartition) IsRoot 

func (p *NormalPartition) IsRoot() bool

func (*NormalPartition) Key 

func (p *NormalPartition) Key() PartitionKey

func (*NormalPartition) Kind 

func (p *NormalPartition) Kind() enumspb.TaskQueueKind

func (*NormalPartition) NamespaceId 

func (p *NormalPartition) NamespaceId() string

func (*NormalPartition) ParentPartition 

func (p *NormalPartition) ParentPartition(degree int) (*NormalPartition, error)

ParentPartition returns a NormalPartition for the parent partition, using the given branching degree.

func (*NormalPartition) PartitionId 

func (p *NormalPartition) PartitionId() int

func (*NormalPartition) RoutingKey 

func (p *NormalPartition) RoutingKey() string

func (*NormalPartition) RpcName 

func (p *NormalPartition) RpcName() string

func (*NormalPartition) TaskQueue 

func (p *NormalPartition) TaskQueue() *TaskQueue

func (*NormalPartition) TaskType 

func (p *NormalPartition) TaskType() enumspb.TaskQueueType

type Partition 

type Partition interface {
	NamespaceId() string
	TaskQueue() *TaskQueue
	TaskType() enumspb.TaskQueueType
	// IsRoot always returns false for Sticky partitions
	IsRoot() bool
	Kind() enumspb.TaskQueueKind

	// RpcName returns the mangled name of the task queue partition, to be used in RPCs.
	//
	// RPC names look like this:
	//
	//  sticky partition:			<sticky name>
	//	root normal partition: 		<task queue name>
	//	non-root normal partition: 	/_sys/<task queue name>/<partition id>
	//
	// This scheme lets users use anything they like for a base name, except for strings
	// starting with "/_sys/", without ambiguity.
	//
	// For backward compatibility, unversioned low-level task queues with partition 0 do not
	// use mangled names, they use the bare base name.
	RpcName() string
	Key() PartitionKey
	// RoutingKey returns the string that should be used to find the owner of a task queue partition.
	RoutingKey() string
}

Partition is a sticky or normal partition of a TaskQueue. Each Partition has a distinct task queue partition manager in memory in Matching service. Normal partition with `partitionId=0` is called the "root". Sticky queues are not considered root.

func PartitionFromPartitionProto 

func PartitionFromPartitionProto(proto *taskqueuespb.TaskQueuePartition, namespaceId string) Partition

func PartitionFromProto 

func PartitionFromProto(proto *taskqueuepb.TaskQueue, namespaceId string, taskType enumspb.TaskQueueType) (Partition, error)

func UnsafePartitionFromProto added in v1.25.0 

func UnsafePartitionFromProto(proto *taskqueuepb.TaskQueue, namespaceId string, taskType enumspb.TaskQueueType) Partition

UnsafePartitionFromProto tries parsing proto using PartitionFromProto but if it fails still returns a Partition object using the raw values in the proto. This method should only be used in logs/metrics, not in the server logic.

type PartitionKey 

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

PartitionKey uniquely identifies a task queue partition, to be used in maps. Note that task queue kind (sticky vs normal) and normal name for sticky task queues are not part of the task queue partition identity.

type StickyPartition 

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

StickyPartition is made by SDK for a single workflow worker to keep workflow tasks of the same execution in the same worker for caching benefits. Each sticky partition is identified by a unique `stickyName` generated by SDK. A StickyPartition can only have workflow task type.

func (*StickyPartition) IsRoot 

func (s *StickyPartition) IsRoot() bool

func (*StickyPartition) Key 

func (s *StickyPartition) Key() PartitionKey

func (*StickyPartition) Kind 

func (s *StickyPartition) Kind() enumspb.TaskQueueKind

func (*StickyPartition) NamespaceId 

func (s *StickyPartition) NamespaceId() string

func (*StickyPartition) RootPartition 

func (s *StickyPartition) RootPartition() Partition

func (*StickyPartition) RoutingKey 

func (s *StickyPartition) RoutingKey() string

func (*StickyPartition) RpcName 

func (s *StickyPartition) RpcName() string

func (*StickyPartition) StickyName 

func (s *StickyPartition) StickyName() string

func (*StickyPartition) TaskQueue 

func (s *StickyPartition) TaskQueue() *TaskQueue

func (*StickyPartition) TaskType 

func (s *StickyPartition) TaskType() enumspb.TaskQueueType

type TaskQueue 

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

TaskQueue represents a logical task queue for a type of tasks (e.g. Activity or Workflow). Under the hood, a TaskQueue can be broken down to multiple sticky or normal partitions.

func (*TaskQueue) Family 

func (n *TaskQueue) Family() *TaskQueueFamily

func (*TaskQueue) Name 

func (n *TaskQueue) Name() string

func (*TaskQueue) NamespaceId 

func (n *TaskQueue) NamespaceId() string

func (*TaskQueue) NormalPartition 

func (n *TaskQueue) NormalPartition(partitionId int) *NormalPartition

func (*TaskQueue) RootPartition 

func (n *TaskQueue) RootPartition() *NormalPartition

func (*TaskQueue) StickyPartition 

func (n *TaskQueue) StickyPartition(stickyName string) *StickyPartition

func (*TaskQueue) TaskType 

func (n *TaskQueue) TaskType() enumspb.TaskQueueType

type TaskQueueFamily 

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

TaskQueueFamily represents the high-level "task queue" that user creates by explicitly providing a task queue name when starting a worker or a workflow. A task queue family consists of separate TaskQueues for different types of task (e.g. Workflow, Activity).

func NewTaskQueueFamily 

func NewTaskQueueFamily(namespaceId string, name string) (*TaskQueueFamily, error)

NewTaskQueueFamily takes a user-provided task queue name (aka family name) and returns a TaskQueueFamily. Returns an error if name looks like a mangled name.

func UnsafeTaskQueueFamily 

func UnsafeTaskQueueFamily(namespaceId string, name string) *TaskQueueFamily

UnsafeTaskQueueFamily should be avoided as much as possible. Use NewTaskQueueFamily instead as it validates the tq name.

func (*TaskQueueFamily) Name 

func (n *TaskQueueFamily) Name() string

func (*TaskQueueFamily) NamespaceId 

func (n *TaskQueueFamily) NamespaceId() string

func (*TaskQueueFamily) TaskQueue 

func (n *TaskQueueFamily) TaskQueue(taskType enumspb.TaskQueueType) *TaskQueue
