from your question am assuming you are ingesting into individual profile class dataset.
from RTCDP perspective, there may not be much impact. profile store will refer to the latest record of the profile as ingested.
from Data lake perspective, yes, there will be impact that huge number of records will be accumulated in dataset, there are license metrics like total data volume which will be impacted.
in general, i do not see any major challenge, but avoid if possible this situation.
if only few attributes with in a profile are changing which is leading you to ingest the full profile attributes frequently, then you can consider isolating only those attributes into another dataset and ingest those attributes. this will avoid ingesting all the attributes frequently.
