compact: if compaction didn't run for a while, it seems to need more and more local disk space about thanos HOT 3 CLOSED

Have you seen #3405? I think it talks about the same problems.

it seems to need more and more local disk space

That shouldn't be true. It just continues doing its work. Unless you are referring to disk space that you are using as "remote object storage"? Then yes. Typically "local disk space" refers to the space used for the compaction work but not for the object storage.

for creating all the level 3 with resolution 300000 it first downloads all the level 3 with resolution 0, is that right?

It does that one by one, compactor doesn't download all raw resolution blocks and downsample them at the same time unless you have downsampling concurrency increased from the default 1.

@GiedriusS Indeed it seems to be the same (or at least cover the same area)... and I hadn't spotted it when skimming through the existing reports.

Can you mark this a duplicate of the other?

Closing as a duplicate of #3405.

@calestyo: feel free to bring some details and information from this issue into #3405 if you find it valuable.
