Steve Kuznetsov fd6c852567 promtool: backfill: allow configuring block duration (#8919) ... * promtool: backfill: allow configuring block duration When backfilling large amounts of data across long periods of time, it may in certain circumstances be useful to use a longer block duration to increase the efficiency and speed of the backfilling process. This patch adds a flag --block-duration-power to allow a user to choose the power N where the block duration is 2^(N+1)h.

A nice message helps here. Signed-off-by: Steve Kuznetsov <skuznets@redhat.com> * backfill: test long block durations A test that uses a long block duration to write bigger blocks is added. The check to make sure all blocks are the default duration is removed. Signed-off-by: Steve Kuznetsov <skuznets@redhat.com>		2021-06-29 14:53:38 +05:30
