# Transactions Topic Documentation

This document provides an overview of the `transactions` topic in the Redpanda cluster. The topic is designed to capture autogenerated transaction events with various attributes.

## Schema Overview

    "index": "integer",
    "price": "string",

    "timestamp": "string",
    "user_id": "integer"
}
```

- **email**: The email address of the user involved in the transaction.
- **index**: A numeric index associated with the transaction. This could represent the position or order of the transaction in a sequence.
