Process Partitioning

Process Partitioning

The Problem

When working with large, high volume, low latency systems, it is often the case that processing data sequentially becomes detrimental to the system's health. If we only allow 1 process to work on our data we run into several challenges:

  • Our process may fall behind resulting in a situation which it is impossible for our process to catch up.
  • Our singleton process could crash and leave our system in a degraded state.
  • The average latency of data processing could be dramatically affected by outlying cases.
