This request is used to refresh leaders info on node User can invoke it by using admin api On some cases leaders_table can not be updated long time So client request can be failed in this cases. New request allows us force leaders table by hand, after it shard should be refresh all info about leaders. After reset leaders info, metadata responce will not contain leaders for all partition during short period of time ~150ms. heartbits delay or leader notification delay.
