Hi, I have a bucket which has been sized for 2.4B objects with a prime number 24xxx index shards. You can't list this bucket but you don't have any large omap issue.

If in doubt, don't click any link nor open any attachment ! ________________________________ Hi all, Does anyone have any guidance on the maximum number of bucket index shards to optimize performance for buckets with a huge number of objects? It seems like there is probably a threshold where performance starts to decrease with an increased number of shards (particularly bucket listings). More specifically, if I have N OSDs in the bucket index pool, does it make sense to allow a bucket to have more than N index shards? Perhaps some multiple of N makes sense, with the value of the multiplier influenced by osd_op_num_threads_per_shard and osd_op_num_shards? Thanks in advance for any theoretical or empirical insights!
