Data processing review

• Batch
  • Great for large sets of data
  • Potentially poor latency
• Queue
  • Awesome to maintain order
  • Can be tricky to manage
• Stream
  • Fantastic for latency / unknown data characteristics
  • Scaling considerations

Complex systems

• Not all processes fit within a single processing type
• Many real-world scenarios may require multiple components to build the best processing model
• Concepts can be applied to various components as required

Vaccination clinic

• Multiple, simultaneous moving pieces
• Vary based on locale and requirements
• Consider a large self-contained clinic
• Concepts apply to smaller pharmacies / doctor's offices as well

Vaccination clinic areas

• Arrival / entrance
  • Entry and temperature check, with a single line
• Registration
  • Check-in & validation on info, multiple registrars
• Vaccine administration
  • Actual application of vaccine, multiple stations

• Monitoring
  • Patients checked for any post-application reactions, many seats
• Departure
  • Exit from clinic

Let's practice!
