* A bug sneaked in the ETA scheduler that made it only able to execute
|
|
|
one task per second(!)
|
|
|
|
|
|
- The scheduler sleeps between iterations so it doesn't consume too much CPU.
|
|
|
- It keeps a list of the scheduled items sorted by time, at each iteration
|
|
|
- it sleeps for the remaining time of the item with the nearest deadline.
|
|
|
- If there are no eta tasks it will sleep for a minimum amount of time, one
|
|
|
- second by default.

+ A bug sneaked in here, making it sleep for one second for every task

|
+ that was scheduled. This has been fixed, so now it should move
|
|
|
+ tasks like hot knife through butter.
|
|
|
+
|
|
|
+ In addition a new setting has been added to control the minimum sleep
|
|
|
+ interval; ``CELERYD_ETA_SCHEDULER_PRECISION``. A good
|
|
|
+ value for this would be a float between 0 and 1, depending
|
|
|
+ on the needed precision. A value of 0.8 means that when the ETA of a task
|
|
|
+ is met, it will take at most 0.8 seconds for the task to be moved to the
|
|
|
+ ready queue.
