InfluxDB as primary metrics storage

[vitaliimelnychuk]

Description

Maestro was started in a quick way where we wanted to validate the idea. There are already great examples of using Maestro with 50k-100k RPS generated load. Having that load and still using MongoDB doesn't make a lot of sense. It's not performant and reliable.

Solution

Changing metrics storage to InfluxDB will allow us to simplify a lot of things and make write/read operations much faster. It will also allow us easily manipulate complex aggregation queries.

Additional information

Having Influxdb also means that we will have one more dependency but I definitely think this is a great price we should pay to improve UX and support bigger performance test executions.
