- `shardReplication`: Enable replicating the Shard. Shard replication will duplicate each shards into replicas to spread the load even more
- `numberOfSoftReplicas`: Number of replicas for the soft tag shards
- `numberOfHardReplicas`: Number of replicas for the hard tag shards
- `regionalReplicationOptions` : This setting enables you to replicate shards across different regions, thereby reducing read latency and distributing the load more evenly. By enabling this option, each shard will be replicated in all available regions. Please note that this will increase the number of Durable Objects (DOs) created and the volume of write requests sent to the DOs.

It would be nice to doc the total numbers of DO somewhere

- `defaultRegion`: The default region to use for the replication.
- `maxWriteRetries`: The number of retries to perform when writing tags
