Thanos compactor "--min-time" parameter not working about thanos HOT 3 OPEN

Your usecase is for the Compactor to compact blocks created after 72h, correct? Based on your expectation, I think you should set max-time rather than min-time.

min-time is to compact blocks created within than a time window.

Hi @yeya24 ,

Thanks for your answer.

Actually, I'm currently working on a setup where I intend to retain only raw data for the first 30 days and then use the compactor to downgrade the data. I envisioned the following configuration for this purpose:

    thanos-compactor:
        image: quay.io/thanos/thanos:v0.30.2
        depends_on:
            - minio
        volumes:
            - ./bucket/:/etc/thanos/
        command:
            - 'compact'
            - '--log.level=debug'
            - '--data-dir=/data'
            - '--objstore.config-file=/etc/thanos/bucket.yaml'
            - '--wait'
            - '--compact.progress-interval=5m'
            - '--retention.resolution-1h=365d'
            - '--retention.resolution-5m=90d'
            - '--retention.resolution-raw=30d'
            - '--min-time=29d' 

For now, I'm just testing if the --min-time parameter works as expected.

According to the thanos documentation :

      --min-time=0000-01-01T00:00:00Z
                                Start of time range limit to compact.
                                Thanos Compactor will compact only blocks, which
                                happened later than this value. Option can be a
                                constant time in RFC3339 format or time duration
                                relative to current time, such as -1d or 2h45m.
                                Valid duration units are ms, s, m, h, d, w, y.

It appears I may have misunderstood the purpose of this parameter. To clarify, does "later" in this context imply a range from the current time up to 72 hours ago? If this interpretation is correct, why aren't my newer blocks (those younger than 72 hours) being compacted from 2-hour blocks to 4-hour/8-hour blocks, etc.?
