How is the deletion_delay and the cleanup_interval are configured?

Do you have bucket index enabled? if not, can you enable it?

[madhaviuddaraju]

yes , we have enabled bucket index.
@alanprot I am facing an issue that after compaction to 24 hours block , we are seeing missing blocks , any configs i need to cross check to fix this?
I have deleted the configs related "out_of_order_time_window: 4h", is this config causing missing blocks after compaction?

[alanprot]

oh.. you are using the OOTO feature?

If so, i think this is the problem: #5402
