In a sharded database architecture, how are Update operations handled across multiple shards?
- Updates are broadcast to all shards
- A central coordinator handles all updates
- Each shard independently handles updates for its data
- Updates are queued and processed sequentially
In a sharded database architecture, a central coordinator (Option 2) often handles updates that affect multiple shards. Each shard (Option 3) independently handles updates for its own data, but coordinated updates across shards typically require a central component. Options 1 and 4 are not common methods for handling updates in sharded databases.
