When it comes to QPS, deleting <em id="obs_faq_0020__i14156327182517">N</em> objects is counted as <em id="obs_faq_0020__i19156127122510">N</em> operations. If a large number of objects named with prefixes in lexicographic order are deleted, lots of requests may be concentrated in a specific partition, which results in hot access. This limits the request rate in the hot partition and increases access delay.</p>

<p id="obs_faq_0020__p75343320100">To address this problem, you can reduce the number of objects in a single batch deletion request, initiate more concurrent requests, and name objects with random prefixes.</p>
