Implementing Caching Strategies

Create an example of implementing caching strategies to improve the performance of SQL queries in a system using RAG components.

<!-- HTML structure to display query results -->
<div id='query-results'></div>

This HTML snippet provides a container where query results will be displayed after fetching from the cache or database.

/* CSS styling for the query results container */
#query-results {
    padding: 10px;
    border: 1px solid #ccc;
    margin-top: 20px;
}

This CSS snippet styles the query results container.

// JavaScript to implement caching strategies
const cache = {};

function executeQuery(sql) {
    // Check if the result exists in the cache
    if (cache[sql]) {
        displayResults(cache[sql]);
        return;
    }

    // If not in cache, execute the SQL query
    database.query(sql).then(results => {
        // Store the results in the cache
        cache[sql] = results;
        // Display the results
        displayResults(results);
    });
}

function displayResults(results) {
    // Display the results in the query-results element
    const resultsContainer = document.getElementById('query-results');
    resultsContainer.innerHTML = JSON.stringify(results, null, 2);
}

// Example SQL query
const sqlQuery = 'SELECT * FROM users';
// Execute the query on page load
window.onload = () => executeQuery(sqlQuery);

This JavaScript snippet includes caching logic and functions to execute and display results of SQL queries. It uses a simple in-memory cache object to store query results.
