partitioning key and number of files created

Hi! Is partitioning key supposed to have an impact on the number of files created? I am seeing a lot of small parquet files created with partitioning key %F/%H%M%S, despite 30s interval and 512MB max file size

Oh yes it is the case, I tried with less granular key and files are created less often now
