This config field is needed for CSS obfuscation. In fact this is the only needed obfuscation config field AFAIK.

What does this PR do?

  • adds a "sql_obfuscation_mode" field to /info endpoint for using it when obfuscating stats in libraries.

Motivation

Describe how you validated your changes

  • unit test
  • system test soon

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

  • ✅ = significantly better comparison variant performance
  • ❌ = significantly worse comparison variant performance
  • ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

  1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

  2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

  3. Its configuration does not mark it "erratic".

…de test

The test was comparing a plain string "" to obfuscate.ObfuscationMode(""),
which caused a type assertion failure with testify's assert.Equal.
Use the correct ObfuscationMode type in the assertion.
