#### 6.2 Task Scheduler
* Base Task Queue
```go
type baseTaskQueue struct {
unissuedTasks *List
activeTasks map[int64]*task
utLock sync.Mutex // lock for UnissuedTasks
atLock sync.Mutex // lock for ActiveTasks
}
func (queue *baseTaskQueue) AddUnissuedTask(task *task)

func (queue *baseTaskQueue) AddActiveTask(task *task)
func (queue *baseTaskQueue) PopActiveTask(id int64) *task
func (queue *baseTaskQueue) TaskDoneTest(ts Timestamp) bool
```
*AddUnissuedTask(task \*task)* will put a new task into *unissuedTasks*, while maintaining the list by timestamp order.
*TaskDoneTest(ts Timestamp)* will check both *unissuedTasks* and *unissuedTasks*. If no task found before *ts*, then the function returns *true*, indicates that all the tasks before *ts* are completed.
* Data Definition Task Queue
```go
type ddTaskQueue struct {
baseTaskQueue
lock sync.Mutex
}
func (queue *ddTaskQueue) Enqueue(task *task) error
func newDdTaskQueue() *ddTaskQueue
```
Data definition tasks (i.e. *CreateCollectionTask*) will be put into *DdTaskQueue*. If a task is enqueued, *Enqueue(task \*task)* will set *Ts*, *ReqId*, *ProxyId*, then push it into *queue*. The timestamps of the enqueued tasks should be strictly monotonically increasing. As *Enqueue(task \*task)* will be called in parallel, setting timestamp and queue insertion need to be done atomically.
* Data Manipulation Task Queue
```go
type dmTaskQueue struct {
baseTaskQueue
}
func (queue *dmTaskQueue) Enqueue(task *task) error
func newDmTaskQueue() *dmTaskQueue
```
Insert tasks and delete tasks will be put into *DmTaskQueue*.
If a *insertTask* is enqueued, *Enqueue(task \*task)* will set *Ts*, *ReqId*, *ProxyId*, *SegIdAssigner*, *RowIdAllocator*, then push it into *queue*. The *SegIdAssigner* and *RowIdAllocator* will later be used in the task's execution phase.
* Data Query Task Queue
```go
type dqTaskQueue struct {
baseTaskQueue
}
func (queue *dqTaskQueue) Enqueue(task *task) error
func newDqTaskQueue() *dqTaskQueue
```
Queries will be put into *DqTaskQueue*.
* Task Scheduler
``` go
type taskScheduler struct {
// definition tasks
ddTasks *task chan
// manipulation tasks
dmTasks *task chan
// query tasks
dqTasks *task chan
DdQueue *ddTaskQueue
DmQueue *dmTaskQueue
DqQueue *dqTaskQueue
tsAllocator *TimestampAllocator
ReqIdAllocator *IdAllocator
}
func (sched *taskScheduler) EnqueueDDTask(task *task) Status
func (sched *taskScheduler) EnqueueDMTask(task *task) Status
func (sched *taskScheduler) EnqueueDQTask(task *task) Status
func (sched *taskScheduler) scheduleDdTask() *task
func (sched *taskScheduler) scheduleDmTask() *task
func (sched *taskScheduler) scheduleDqTask() *task
func (sched *taskScheduler) Start() error
func (sched *taskScheduler) TaskDoneTest(ts Timestamp) bool
func newTaskScheduler(ctx context.Context, tsAllocator *TimestampAllocator, ReqIdAllocator *IdAllocator) *taskScheduler
```
*scheduleDdTask()* selects tasks in a FIFO manner, thus time order is garanteed.
The policy of *scheduleDmTask()* should target on throughput, not tasks' time order. Note that the time order of the tasks' execution will later be garanteed by the timestamp & time tick mechanism.
The policy of *scheduleDqTask()* should target on throughput. It should also take visibility into consideration. For example, if an insert task and a query arrive in a same time tick and the query comes after insert, the query should be scheduled in the next tick thus the query can see the insert.
*TaskDoneTest(ts Timestamp)* will check all the three task queues. If no task found before *ts*, then the function returns *true*, indicates that all the tasks before *ts* are completed.

* EnqueueDMTask
If a insertTask is enqueued, *EnqueueDDTask(task \*task)* will set *Ts*, *ReqId*, *ProxyId*, *SegIdAssigner*, *RowIdAllocator*, then push it into queue *dmTasks*. The *SegIdAssigner* and *RowIdAllocator* will later be used in the task's execution phase.
#### 6.3 Time Tick
* Time Tick
``` go
type timeTick struct {
lastTick Timestamp
currentTick Timestamp
wallTick Timestamp
tickStep Timestamp
syncInterval Timestamp
tsAllocator *TimestampAllocator
scheduler *taskScheduler
ttStream *MessageStream
ctx context.Context
}
func (tt *timeTick) tick() Status
func (tt *timeTick) Start() error
func (tt *timeTick) synchronize() error
func newTimeTick(ctx context.Context, tickStep Timestamp, syncInterval Timestamp, tsAllocator *TimestampAllocator, scheduler *taskScheduler, ttStream *MessageStream) *timeTick
```
*Start()* will enter a loop. On each *tickStep*, it tries to send a *TIME_TICK* typed *TsMsg* into *ttStream*. After each *syncInterval*, it sychronizes its *wallTick* with *tsAllocator* by calling *synchronize()*. When *currentTick + tickStep < wallTick* holds, it will update *currentTick* with *wallTick* on next tick. Otherwise, it will update *currentTick* with *currentTick + tickStep*.
