IStorageSink

IStorageSink defines the interface for persisting executed orders and related trading data. It abstracts away the underlying storage mechanism (e.g. MongoDB, binary log, cloud).

class IStorageSink : public ISubsystem {
public:
  virtual ~IStorageSink() = default;
  virtual void store(const Order& order) = 0;
};

Purpose

• Persist orders for post-trade audit, reconciliation, analytics, or compliance.

Responsibilities

Method	Description
store	Persists the provided Order object.

Notes

• Called when orders are filled, canceled, or otherwise finalized.
• Backends may include MongoDB, file-based logs, or in-memory mirrors.
• Integrated via ISubsystem for lifecycle control and flush handling.
