Hash sharding hotspot risk
Why is hash-based sharding generally preferred over range sharding for uniform write distribution?
Options
- 1It spreads keys uniformly, avoiding hot spots from sequential or skewed key ranges
- 2It supports efficient range scans, since hash partitioning keeps adjacent keys on one shard
- 3It requires no rebalancing ever, because hashing keeps shard assignment fixed despite node changes
- 4It preserves key ordering across shards, so a range query hits a contiguous span
