Disclosed herein are system, method, and computer program product embodiments for minimizing table lock duration during lost change resynchronization between a source table and a replica table. An embodiment operates by detecting a restart at a source node or a replica node. A source table at the source node is then locked based on the detection. A database transaction is then created for a lost change resynchronization operation and the source table is unlocked. The database transaction is then compared to another database transaction based on its timestamp. Based on the comparison, either the database transaction for the lost change resynchronization operation or the other database transaction is executed.

Data synchronization with minimal table lock duration in asynchronous table replication

An apparatus including a first speaker configured to output higher-frequency sound from among sound of a channel via at least one slit, and a second speaker configured to output lower-frequency sound from among the sound of the channel via at least one other slit. The at least one slit may have a thickness that is less than a wavelength of sound emitted.

Method and apparatus for outputting sound through speaker

An audio system, an audio outputting method, and a speaker apparatus are disclosed. The audio system includes a plurality of speaker modules connected to each other, a detection module configured to detect information of the plurality of speaker modules and user information, and a home control module configured to receive an audio signal, process the received audio signal based on the information of the plurality of speaker modules and the user information, and transmit the processed audio signal to the plurality of speaker modules.
