1. A method comprising:
obtaining hot data managed by a first cluster, wherein the first cluster comprises at least one first single-threaded main controller;
processing, at the at least one single-threaded main controller, an access request at a time, wherein the access request requests data;
obtaining a migration condition that indicates the hot data is to be migrated to a second cluster, wherein the second cluster comprises at least one second single-threaded main controller, and wherein the second cluster manages second hot data that is migrated according to the migration condition;
reading a key corresponding to the hot data from the first cluster;
obtaining a first hash slot in the second cluster based on the key;
migrating, in response to the migration condition being met, the hot data and the key to the first hash slot in the second cluster; and
triggering, in response to the migration condition being met, a first update of a first access path of the hot data.
