is there a way to backfill data? in other words: I want to remove records from last year but did not have the TTL attribute in place, now I do... can I update those rows and then have the process remove last years data?

TTL does not use burst capacity. Burst capacity is used with the table-level Adaptive Capacity feature and has nothing to do with TTL. Since they are background process, TTL processes will only start if their running won't interfere with customer table operations and there are a few internal types of system capacity that need to be available as well. As it is meant not to affect production table operations, TTL therefore has secondary or even tertiary priority for resources.
