Time-Series DatabasesIn the context of industrial automation
For example, process history within a SCADA system.
Storing massive amounts of time-stamped sensor data,
events, user inputs.
Query and processing for visualizations, reports, analyses,
optimzation applications.
Important properties other than scalability:
Durable storage
High availability
Fault tolerance
Fast / near-real time queries

Load Scenarios
Phasor Measurement Unit (PMU)
Installations to grow in the smart grid
area to stabalize power grid.

synchrophasor-boom
Benchmark scenario:
Every second, a PMU uploads 15
float values of a sinus curve per 20ms
(750 values/s).
PMU uploads are distributed over
time.

Load Scenarios
Distribution of Smart Meters
increases rapidly
Data is gathered by
aggregators and then
forwarded to the backend
system.
Benchmark scenario:
Every 15 minutes, a smart meter
sends 1 float.
All smart meter uploads happen in
a 2 minute window every 15
minutes.

Benchmark Results
Linear scalability: KairosDB, showed a
good near-linear scaling behaviour.
Industrial workloads: KairosDB was
able to handle both workloads with
realistic cluster sizes
Workload independence: For both
types of industrial workloads KairosDB
scaled in a similar, linear way.
Resiliency: Even with one or two
instances down KairosDB could
continue working.
Read/write independence: Combined
read/write throughput even above the
write only performance.

• Experiment 1 :
• Running cloud based soft-PLC
application without enabling
automatic scaling
• Roundtrip time exceeds 1000ms
during over load condition
• Experiment 2 :
• Running cloud based soft-PLC
application with automatic
scaling enabled
• Roundtrip time exceeds 1000ms
only before scaling
