Performance Considerations

Prevent unbounded memory growth:

MerchantComponent:
  MaxNonceCacheSize = 1000          // Keep last 1000 nonces

Old nonces are automatically pruned when limit exceeded.

Prevent unbounded log growth:

MerchantComponent:
  MaxTransactionLogSize = 10000     // Keep last 10000 transactions

Set to 0 for unlimited (if using external analytics).

Only essential data replicates:

Transaction logs and nonces are server-only.
