System for changing rules for data pipeline reading using trigger data from one or more data connection modules

A system including a first data processing module, a second data processing module, and one or more data connection modules that transfer data between the first data processing module and the second data processing module, the system comprising:

• a processor;
• and
• one or more computer readable mediums collectively including instructions that, when executed by the processor, cause the processor to:
• in an operational state where the first data processing module and the second data processing module can process data input thereto, cause the first data processing module to input trigger data to the one or more data connection modules;
• and
• in response to the second data processing module receiving the trigger data via the one or more data connection modules, cause the second data processing module to change a reading rule for reading data from the one or more data connection modules;
• wherein before the second data processing module receives the trigger data via the one or more data connection modules, the second data processing module is informed in advance concerning the reading rule to be used by the second data processing module in response to the trigger data.
