compact: Added support for no-compact markers in planner. #3409
Conversation
The planner algo was adapted to avoid unnecessary changes to blocks caused by excluded blocks, so we can quickly switch to different planning logic in next iteration. Fixes: #1424 Signed-off-by: Bartlomiej Plotka <bwplotka@gmail.com>

Why a block with the max minTime is just uploaded? It is possible that it was uploaded several days ago, but has the max minTime. WDYT?

This is exactly what this comment says right? That it has max of minTimes of all blocks, no?

For example, if we stop adding new blocks to a bucket, and the latest block in the bucket was uploaded 3 days ago. So we also want to exclude the latest block in this case?
The comment mentions recently created block so seems to check the block creation time makes more sense. Maybe I miss something

We mean the freshest TBH
also the whole check is really not super needed for us. It's relevant to Prometheus, but let's keep it 🤗

Ok. If it is relevant to Prometheus then it makes sense 👍

The planner algo was adapted to avoid unnecessary changes to
blocks caused by excluded blocks, so we can quickly switch to
different planning logic in the next iteration.
Fixes: #1424
The idea is to have
no-compact-mark.jsonin each block that has to be excluded from compaction. cc @SuperQSigned-off-by: Bartlomiej Plotka bwplotka@gmail.com
