Large beauty and charm cross-sections make the LHC an ideal place to study the physics of heavy flavour, but the rate of signals of interest to the LHCb experiment, particularly after LS2, mean that a conventional trigger design with further offline reconstruction would overwhelm the available computing resources. In this seminar I will describe the novel approaches LHCb is using in the trigger to reconstruct and select only the data required for analysis in Run 3, several of which have already been put into operation during Run 2. .
