Synchronizing a cursor based on consumer and producer throughputs

A system comprising:

• a memory having computer readable instructions;
• and
• one or more processors for executing the computer readable instructions, the computer readable instructions comprising:
• writing, by a producer, data to one or more buffers, the one or more buffers comprising a plurality of cells and together forming a circular buffer, wherein an input cursor indicates which cell of the plurality of cells the producer writes to;
• reading, by a consumer, data from the one or more buffers, wherein an output cursor indicates which cell of the plurality of cells the consumer reads from;
• detecting that the consumer is overrun by the producer;
• comparing a throughput of the consumer to a throughput of the producer, responsive to the detecting that the consumer is overrun by the producer;
• and
• synchronizing the output cursor to a new position, the new position being selected based on the comparing the throughput of the consumer to the throughput of the producer.

A computer program product for synchronizing an output cursor of a consumer, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• writing, by a producer, data to one or more buffers, the one or more buffers comprising a plurality of cells and together forming a circular buffer, wherein an input cursor indicates which cell of the plurality of cells the producer writes to;
• reading, by a consumer, data from the one or more buffers, wherein an output cursor indicates which cell of the plurality of cells the consumer reads from;
• detecting that the consumer is overrun by the producer;
• comparing a throughput of the consumer to a throughput of the producer, responsive to the detecting that the consumer is overrun by the producer;
• and
• synchronizing the output cursor to a new position, the new position being selected based on the comparing the throughput of the consumer to the throughput of the producer.
