Stream TTL is set to 3 days and any messages that reach 3 days TTL are marked for soft delete/compaction.
My understanding is expired messages are deleted once every 24 hours and marked for compaction.
Question : When does the actual reclaim disk space happens ?
Solved! Go to Solution.

SolutionThe time-to-live (TTL) for messages means that messages persist in the partitions of a stream topic for a specific time period. During that time, messages can be read or re-read by consumers. Once the TTL for a message expires, the message is marked for deletion.
If the TTL is set to 24 hours, expired messages are deleted once every 24 hours.
Run the purge process, removing messages that are marked for deletion and reclaiming disk space.
e.g) maprcli stream purge -path <Stream Path>

Re: When does the actual reclaim disk space happens when stream is TTL'd
Also be aware that running `maprcli stream info -path ...` will kick the space reclaimation into action, in the background, which might lead to heavy I/O if it hasn't run for a while. We've noticed this effect particularly on streams with a TTL of one day or less.
