Parsing with an MCAP Index (opens in new tab)

Welcome to the sixth and final part of our series on MCAP parsing. In the first four parts, we did all the work to parse certain topic messages from a bag file, going through the file sequentially. In the fifth part, we set up a lot of infrastructure to allow ourselves to instead parse the file using indexing so we can get our messages faster. In this part, we’ll finish the process and see how much faster our code is!
