Functions

func NewService

func NewService(params *service.BootstrapParams) common.Daemon

NewService builds a new cadence-matching service

Types

type Config

type Config struct {
	PersistenceMaxQPS dynamicconfig.FloatPropertyFn
	EnableSyncMatch   dynamicconfig.BoolPropertyFnWithTaskListInfoFilters
	RPS               dynamicconfig.IntPropertyFn

	// taskListManager configuration
	RangeSize                 int64
	GetTasksBatchSize         dynamicconfig.IntPropertyFnWithTaskListInfoFilters
	UpdateAckInterval         dynamicconfig.DurationPropertyFnWithTaskListInfoFilters
	IdleTasklistCheckInterval dynamicconfig.DurationPropertyFnWithTaskListInfoFilters
	MaxTasklistIdleTime       dynamicconfig.DurationPropertyFnWithTaskListInfoFilters
	// Time to hold a poll request before returning an empty response if there are no tasks
	LongPollExpirationInterval dynamicconfig.DurationPropertyFnWithTaskListInfoFilters
	MinTaskThrottlingBurstSize dynamicconfig.IntPropertyFnWithTaskListInfoFilters

	// taskWriter configuration
	OutstandingTaskAppendsThreshold dynamicconfig.IntPropertyFnWithTaskListInfoFilters
	MaxTaskBatchSize                dynamicconfig.IntPropertyFnWithTaskListInfoFilters
}

Config represents configuration for cadence-matching service

func NewConfig

func NewConfig(dc *dynamicconfig.Collection) *Config

NewConfig returns new service config with default values

type Engine

type Engine interface {
	Stop()
	AddDecisionTask(addRequest *m.AddDecisionTaskRequest) error
	AddActivityTask(addRequest *m.AddActivityTaskRequest) error
	PollForDecisionTask(ctx context.Context, request *m.PollForDecisionTaskRequest) (*m.PollForDecisionTaskResponse, error)
	PollForActivityTask(ctx context.Context, request *m.PollForActivityTaskRequest) (*workflow.PollForActivityTaskResponse, error)
	QueryWorkflow(ctx context.Context, request *m.QueryWorkflowRequest) (*workflow.QueryWorkflowResponse, error)
	RespondQueryTaskCompleted(ctx context.Context, request *m.RespondQueryTaskCompletedRequest) error
	CancelOutstandingPoll(ctx context.Context, request *m.CancelOutstandingPollRequest) error
	DescribeTaskList(ctx context.Context, request *m.DescribeTaskListRequest) (*workflow.DescribeTaskListResponse, error)
}

Engine exposes interfaces for clients to poll for activity and decision tasks.

func NewEngine

func NewEngine(taskManager persistence.TaskManager,
	historyService history.Client,
	config *Config,
	logger bark.Logger,
	metricsClient metrics.Client,
	domainCache cache.DomainCache,
) Engine

NewEngine creates an instance of matching engine

type Handler

type Handler struct {
	service.Service
	// contains filtered or unexported fields
}

Handler - Thrift handler inteface for history service
