Is using the MEMORY engine in MySQL a viable option for storing chat data temporarily?

Storing chat data temporarily in the MEMORY engine in MySQL can be a viable option as it allows for faster read and write operations since the data is stored in memory. However, it's important to note that data stored in the MEMORY engine is volatile and will be lost when the server restarts. Therefore, it should only be used for temporary storage of chat data that doesn't need to be persisted long-term. 

// Connect to MySQL database using MEMORY engine
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "mydatabase";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Create table using MEMORY engine for storing chat data
$sql = "CREATE TABLE chat_data (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    message VARCHAR(255) NOT NULL,
    timestamp TIMESTAMP
) ENGINE=MEMORY";

if ($conn->query($sql) === TRUE) {
    echo "Table chat_data created successfully";
} else {
    echo "Error creating table: " . $conn->error;
}

// Close connection
$conn->close();
