Types

type ConcurrencyManager

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

func (*ConcurrencyManager) Cleanup

func (c *ConcurrencyManager) Cleanup()

type ConcurrencyResults

type ConcurrencyResults struct {
	*v1.RunConcurrencyResult

	TenantId pgtype.UUID
}

type Extensions

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

func (*Extensions) Add

func (e *Extensions) Add(ext SchedulerExtension)

func (*Extensions) Cleanup

func (e *Extensions) Cleanup() error

func (*Extensions) PostAssign

func (e *Extensions) PostAssign(tenantId string, input *PostAssignInput)

func (*Extensions) ReportSnapshot

func (e *Extensions) ReportSnapshot(tenantId string, input *SnapshotInput)

func (*Extensions) SetTenants

func (e *Extensions) SetTenants(tenants []*dbsqlc.Tenant)

type LeaseManager

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

LeaseManager is responsible for leases on multiple queues and multiplexing queue results to callers. It is still tenant-scoped.

type PostAssignInput

type PostAssignInput struct {
	HasUnassignedStepRuns bool
}

type QueueResults

type QueueResults struct {
	TenantId pgtype.UUID
	Assigned []*v1.AssignedItem

	Unassigned         []*sqlcv1.V1QueueItem
	SchedulingTimedOut []*sqlcv1.V1QueueItem
	RateLimited        []*v1.RateLimitResult
}

type Queuer

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

func (*Queuer) Cleanup

func (q *Queuer) Cleanup()

type Scheduler

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

Scheduler is responsible for scheduling steps to workers as efficiently as possible. This is tenant-scoped, so each tenant will have its own scheduler.

type SchedulerExtension

type SchedulerExtension interface {
	SetTenants(tenants []*dbsqlc.Tenant)
	ReportSnapshot(tenantId string, input *SnapshotInput)
	PostAssign(tenantId string, input *PostAssignInput)
	Cleanup() error
}

type SchedulingPool

type SchedulingPool struct {
	Extensions *Extensions
	// contains filtered or unexported fields
}

SchedulingPool is responsible for managing a pool of tenantManagers.

func NewSchedulingPool

func NewSchedulingPool(repo v1.SchedulerRepository, l *zerolog.Logger, singleQueueLimit int) (*SchedulingPool, func() error, error)

func (*SchedulingPool) GetConcurrencyResultsCh

func (p *SchedulingPool) GetConcurrencyResultsCh() chan *ConcurrencyResults

func (*SchedulingPool) GetResultsCh

func (p *SchedulingPool) GetResultsCh() chan *QueueResults

func (*SchedulingPool) NotifyConcurrency

func (p *SchedulingPool) NotifyConcurrency(ctx context.Context, tenantId string, strategyIds []int64)

func (*SchedulingPool) NotifyQueues

func (p *SchedulingPool) NotifyQueues(ctx context.Context, tenantId string, queueNames []string)

func (*SchedulingPool) Replenish

func (p *SchedulingPool) Replenish(ctx context.Context, tenantId string)

func (*SchedulingPool) SetTenants

func (p *SchedulingPool) SetTenants(tenants []*dbsqlc.Tenant)

type SlotCp

type SlotCp struct {
	WorkerId string
	Used     bool
}

type SlotUtilization

type SlotUtilization struct {
	UtilizedSlots    int
	NonUtilizedSlots int
}

type SnapshotInput

type SnapshotInput struct {
	Workers               map[string]*WorkerCp
	WorkerSlotUtilization map[string]*SlotUtilization
}

type WorkerCp

type WorkerCp struct {
	WorkerId string
	MaxRuns  int
	Labels   []*sqlcv1.ListManyWorkerLabelsRow
}
