(druid) branch master updated: Set default `KillUnusedSegments` duty to coordinator's indexing period & `killTaskSlotRatio` to 0.1 (#16247)
This is an automated email from the ASF dual-hosted git repository.
abhishekrb pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/druid.git
The following commit(s) were added to refs/heads/master by this push:
new 041d0bff5e0 Set default `KillUnusedSegments` duty to coordinator's indexing period & `killTaskSlotRatio` to 0.1 (#16247)
041d0bff5e0 is described below
commit 041d0bff5e0c983660a8eaaf72fd3b9aedf9f976
Author: Abhishek Radhakrishnan <ab...@gmail.com>
AuthorDate: Sun Apr 14 18:56:17 2024 -0700
Set default `KillUnusedSegments` duty to coordinator's indexing period & `killTaskSlotRatio` to 0.1 (#16247)
The default value for druid.coordinator.kill.period (if unspecified) has changed from P1D to the value of druid.coordinator.period.indexingPeriod. Operators can choose to override druid.coordinator.kill.period and that will take precedence over the default behavior.
The default value for the coordinator dynamic config killTaskSlotRatio is updated from 1.0 to 0.1. This ensures that that kill tasks take up only 1 task slot right out-of-the-box instead of taking up all the task slots.
* Remove stale comment and inline canDutyRun()
* druid.coordinator.kill.period defaults to druid.coordinator.period.indexingPeriod if not set.
- Remove the default P1D value for druid.coordinator.kill.period. Instead default
druid.coordinator.kill.period to whatever value druid.coordinator.period.indexingPeriod is set
to if the former config isn't specified.
- If druid.coordinator.kill.period is set, the value will take precedence over
druid.coordinator.period.indexingPeriod
* Update server/src/test/java/org/apache/druid/server/coordinator/DruidCoordinatorConfigTest.java
* Fix checkstyle error
* Clarify comment
* Update server/src/main/java/org/apache/druid/server/coordinator/DruidCoordinatorConfig.java
* Put back canDutyRun()
* Default killTaskSlotsRatio to 0.1 instead of 1.0 (all slots)
* Fix typo DEFAULT_MAX_COMPACTION_TASK_SLOTS
* Remove unused test method.
* Update default value of killTaskSlotsRatio in docs and web-console default mock
* Move initDuty() after params and config setup.
