Environment

- Milvus version: 2.4&2.5&master

- SDK version(e.g. pymilvus v2.0.0rc2):
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU: 
- Others:

Current Behavior

When inserts happen too quickly, segments may not have time to seal, resulting in the allocation of segments with maxRows (2.5GB). However, the ideal segment size should be maxRows * sealProportion.
