--------------------------------------
Summary: Smooth decrease WAL write speed if low work segments left
Key: IGNITE-7584
URL: https://issues.apache.org/jira/browse/IGNITE-7584
Project: Ignite
Issue Type: Task
Components: persistence
Reporter: Dmitriy Pavlov
Assignee: Dmitriy Pavlov
Smooth decrease of the write speed in WAL when approaching the exhaustion of
current segments in the working directory.
Now archiver segment switch involves file copying and may be bottleneck of
speed of grid operation.
Now if out of work segments occurs, grid put speed drop down to 0 ops/sec
ocurred.
This isssue was fixed under IGNITE-7017 with providing new 'NoArchvier' mode,
but in case archiver based WAL is already used by end-user, it is required to
have opportunity to smooth decrease speed instead of drop to 0.
