Techniques for migrating a stateful workload between a source container cluster and a destination container cluster that have different storage backends are provided. In one set of embodiments, these techniques involve creating and running, at the time of the migration, transfer processes in the source and destination container clusters respectively, where (1) the source-side transfer process mounts the workload's persistent volumes (referred to as source persistent volumes) in the source container cluster, and (2) the destination-side transfer process mounts destination persistent volumes that have been dynamically provisioned in the destination container cluster in accordance with the specifications of the source persistent volumes. Upon being created and run, the source-side and destination-side transfer processes can work in concert to securely copy the data in the source persistent volumes to their corresponding destination persistent volumes, thereby transferring that data between the storage backends of the source and destination container clusters.

Migrating stateful workloads between container clusters with different storage backends

A method realizes synchronous playing of audio data from an audio source by two or more wireless speakers. The method includes receiving at each of the wireless speakers first audio data packets sent by the audio source and determining a respective first time point for the receiving of the first audio data packets; processing the first audio data packets at each of the wireless speakers to generate respective second audio data packets, the second audio data packets each including audio data to be played with a fixed data length; setting a delayed play time and obtaining a playing time point at each of the wireless speakers, the obtaining of the playing time point being based on the respective first time point and the respective delayed play time; and playing the second audio data packets at each of the wireless speakers at the respective playing time point.
