Added

• Bundle typescript types declaration into one file.

Changed

• Improve interleaved weighted round robin worker choice strategy implementation.

[2.6.37] - 2023-08-28

Fixed

• Ensure unused worker usage statistics are deleted at runtime.

Changed

• Rename worker choice strategy options choiceRetries to retries.
• Avoid unnecessary branching in worker choice strategies.

[2.6.36] - 2023-08-27

Fixed

• Fix pool execute() arguments check.

Changed

• Make continuous tasks stealing algorithm less aggressive.
• Fine tune tasks stealing algorithm under back pressure.

[2.6.35] - 2023-08-25

Fixed

• Don't account worker usage statistics for tasks that have failed.
• Fix pool information runtime and wait time median computation.

Changed

• Update simple moving average implementation to use a circular buffer.
• Update simple moving median implementation to use a circular buffer.
• Account for stolen tasks in worker usage statistics and pool information.

Added

• Continuous tasks stealing algorithm.

[2.6.34] - 2023-08-24

Fixes

• Avoid cascading tasks stealing under back pressure.

Changed

• Add fastpath to queued tasks rescheduling.

[2.6.33] - 2023-08-24

Fixed

• Fix queued tasks rescheduling.

Changed

• Rename tasks queue options queueMaxSize to size.

Added

• Task stealing scheduling algorithm if tasks queueing is enabled.

[2.6.32] - 2023-08-23

Fixed

• Ensure no task can be executed when the pool is destroyed.

Added

• Add queueMaxSize option to tasks queue options.
• Add O(1) deque implementation implemented with doubly linked list and use it for tasks queueing.
• Add tasks stealing algorithm when a worker node queue is back pressured if tasks queueing is enabled.

[2.6.31] - 2023-08-20

Fixed

• Fix worker choice strategy retries mechanism in some edge cases.

Changed

• Make orthogonal worker choice strategies tasks distribution and created dynamic worker usage.
• Remove the experimental status of the LEAST_ELU worker choice strategy.

[2.6.30] - 2023-08-19

Fixed

• Ensure pool event backPressure is emitted.
• Ensure pool event full is emitted only once.
• Ensure worker node cannot be instantiated without proper arguments.

[2.6.29] - 2023-08-18

Fixed

• Fix race condition between readiness and task functions worker message handling at startup.
• Fix duplicate task function worker usage statistics computation per task function.
• Update task function worker usage statistics if and only if there's at least two different task functions.
• Fix race condition at task function worker usage executing task computation leading to negative value.

Added

• Add back pressure detection on the worker node queue. Event backPressure is emitted when all worker node queues are full (worker node queue size >= poolMaxSize^2).
• Use back pressure detection in worker choice strategies.
• Add worker choice strategies retries mechanism if no worker is eligible.
