Morphology
The phrase combines 'cavalry' (soldiers/reinforcements) with 'showed up' (arrived), so a learner who knows both words can infer that reinforcements or help have arrived. Although it can be used metaphorically for non-military assistance, the core meaning is directly derivable from the constituents and follows a common composition pattern.
Etymology
The cavalry showed up comes from soldiers on horses, the cavalry, arriving at a battle just in time to help. When those riders came at the right moment they could save the day, so the phrase now means 'help or rescue has arrived'.
