Hi, all! We are trying to utilize omap to store kv map. However, we couldn't find a proper way to scan a certain key range of omap. We do can use arg `max_return' to finish this job by iterating . But if `max_return' is set too large, then there will be io waste while the number of keys is few. On the contrary, if it is set too small, then there will also be waste while the number of keys is too many. Is there any solution? -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
