Most APM solutions which analyze and store traces will sample traces to manage the volume of traces stored/analyzed (millions per day!).
Instana claims to store and analyze all traces without sampling. I have been doing some research around Instana, but do not see any whitepaper/blog post that hints at how they accomplish this. Wondering if there is a whitepaper / seminar I have missed that may have hinted at this.
For example, Lightstep has a similar claim and does so through its satellite architecture - they provide a high level explanation of how they try and capture 100% of traces (temporarily).
Does the community here have any good hypothesis - high level - how Instana approaches the challenge?
