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.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
