HQebupt opened a new pull request, #3976:
URL: https://github.com/apache/bookkeeper/pull/3976
### Motivation
The purpose of this feature is to provide more flexibility and control over
the compaction process in the Bookkeeper server by allowing users to configure
the read rate of compaction according to their specific requirements.
It adds support for configuring the read rate of compaction in bytes per
second.
In our production environment of Bookkeeper, we have set
compactionRateByBytes=30M. However, we have observed that it only limits the
write speed to disk and does not limit the read speed from disk. In our
environment, the continuous saturation of disk IO for reads in compaction is
causing issues with data consumption from the disk.
```
// Set the rate at which compaction will readd entries. The unit is bytes
added per second.
compactionRateByBytes=31457280
```
### Changes
- In the `GarbageCollectorThread` class, a new field
`compactionReadByteRateLimiter` of type RateLimiter is added to control the
read rate of compaction.
- In the `ServerConfiguration` class, a new configuration property
`COMPACTION_READ_RATE_BY_BYTES` is defined to specify the read rate of
compaction in bytes per second.
