  • Patent number: 11310297
    Abstract: A method includes receiving from a transmitting data interface, a data stream mapping of a data input into data shards for transmission in a data stream over a data stream communication channel. Data capacity for a data producing software application from a plurality of data producing software applications is adjusted by increasing or decreasing a number of data shards in the data stream assigned to the data producing software application. An updated data stream mapping of the data input into the plurality of data shards is generated by updating a start hash key and an end hash key in a range for each of the data shards assigned to the data producing software application. The updated data stream mapping is sent to the transmitting data interface for adjusting the data capacity in the data stream transmitted over the data stream communication channel of the data producing software application.
