If you have 5 partitions and 3 consumers in one consumer group, the
consumers will balance all 5 partitions such that 2 consumers will get data
from 2 partitions each and 1 consumer will get data from remaining 5th
partition.
If you have 3 partitions and 5 consumers in one consumer group, 3 consumers
will become leader for the 3 partitions(1 partition per consumer) and 2
consumers will starve. Refer to
