Method and apparatus for processing data

An apparatus for processing data, comprising:

• at least one processor;
• and
• a memory storing instructions, the instructions when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• acquiring a to-be-adjusted number of target execution units, the target execution unit referring to a unit executing a target program segment in a stream computing system;
• adjusting a number of the target execution units in the stream computing system based on the to-be-adjusted number;
• and
• determining, for a target execution unit in at least one target execution unit after the adjustment, an identifier set corresponding to the target execution unit, an identifier in the identifier set being used to indicate to-be-processed data;
• and process, through the target execution unit, the to-be-processed data indicated by the identifier in the corresponding identifier set.

A non-transitory computer readable medium, storing a computer program, wherein the computer program, when executed by a processor, causes the processor to perform operations, the operations comprising:

• acquiring a to-be-adjusted number of target execution units, the target execution unit referring to a unit executing a target program segment in a stream computing system;
• adjusting a number of the target execution units in the stream computing system based on the to-be-adjusted number;
• and
• determining, for a target execution unit in at least one target execution unit after the adjustment, an identifier set corresponding to the target execution unit, an identifier in the identifier set being used to indicate to-be-processed data;
• and processing, through the target execution unit, the to-be-processed data indicated by the identifier in the corresponding identifier set.
