how can I manually do a compaction?

[Dumitru-Nicolae Marasoui <ni...@ovoenergy.com>]

Hi, how can I manually do a compaction? (in a local laptop setup)
Is there a command line for this, or certain broker settings to look for?
Thank you,

Hi Nicolae,

Nope, the log cleaner is a thread that runs in the background periodically.
Also be aware that it only compacts log segments that are no longer being
written to - and the default size for a log segment and default log roll
time are both very high, so you won't be seeing log compaction in a testing
environment without changing those broker settings: log.segment.bytes and
log.roll.ms

You'd probably also want to set log.cleaner.max.compaction.lag.ms to a low
figure to allow the log cleaner to aggressively clean in a testing
situation.

Cheers,
