----------------------------------
Summary: Refactor Pages Write Throttling: introduce exponential
throttle as separate class
Key: IGNITE-7901
URL: https://issues.apache.org/jira/browse/IGNITE-7901
Project: Ignite
Issue Type: Improvement
Affects Versions: 2.5
Reporter: Ivan Rakov
Assignee: Dmitriy Pavlov
After IGNITE-7751 fix, we have three incarnations of Pages Write Throttle:
1) Only checkpoint buffer throttling - always on
2) Ratio based throttling - legacy
3) Speed based throttling - default when throttling is enabled
However, all three options use exponential throttling for preventing checkpoint
buffer overflow (see PagesWriteSpeedBasedThrottle.ThrottleMode#EXPONENTIAL
usages and isPageInCheckpoint branch of PagesWriteThrottle).
For the sake of getting rid of copypaste, it would be better to refactor this
and introduce exponential throttling to separate class. Two callbacks now will
be called instead of one, but code will become nicer.
