-In this configuration, the `Match_regex` rule is set to `.*_sensor_[AB]`. This regular expression matches any `Tag` that ends with `_sensor_A` or `_sensor_B`, regardless of what precedes it. This approach provides a more flexible and powerful way to handle different source tags with a single routing rule.
