Scalability of azure redis example

Question

I built an auction site with a dynamic caching layer after I seeing how expensive a dbaas is. The site is now done, but like any site that grows, my caching solution grew too. The cache currently caches every page on the site so I made sure everything gets invalidated appropriately, but the amount of stuff I'm invalidating has grown. More specifically when I'm creating a new auction. I know I'm using Azure so I can scale things from the portal to handle load, but I wanted to make sure my design will work. When someone creates an auction listing, I have to invalidate a bunch of stuff like in code below. Does anyone see a problem with what I'm doing or should I be good?

I'm using redis-delete-wildcard for the delwild keyword

var Post = require('../models/post');
let emails;
var startTime;
const redis = require('redis');
var redisConnection = require("../connections/server");
require('redis-delete-wildcard')(redis); //pass in redis so prototype can be extended
const checkAuth = require('../middleware/check-auth');
module.exports = function (context, req) {
 checkAuth(context, req);
 const tempAuctionKey = `temp-auction-data-${req.body.creator}`;
 redisConnection.client.get(tempAuctionKey, function (err, result) {
 let blacklistGroup;
 let email;
 if (err) {
 console.log(err);
 }
 let output = JSON.parse(result);
 email = output.documents.email;
 emails = output.emails;
 if (err) {
 context.res = {
 status: 500,
 body: {
 message: "FAILED TO GET TEMP AUCTION DATA FROM CACHE!",
 error: err
 },

 };
 context.done();
 }
 var fiveDaysAfterAuction = new Date(req.body.auctionEndDateTime * 1000);
 startTime = new Date(req.body.startTime);
 startTime.setSeconds(0);
 fiveDaysAfterAuction.setHours(120);
 console.log("req.body.auctionImages");
 console.log(req.body.images);
 let images = req.body.images;
 console.log("req.body.auctionImagesTimeStamp");
 console.log(req.body.auctionImagesTimeStamp);
 const post = new Post({
 title: req.body.title,
 creator: req.body.creator
 //and more...
 });
 post.save().then(result => {
 const totalListingsKey = `dashboardTotal-${req.body.creator}`;
 const sellerDashboardKey = `dashboard-${req.body.creator}-*`;
 const bioKey = `my-bio-${req.body.sellerName}-*`;
 const mainListingsCountKey = `main-listing-count`;
 const buyNowTotalKey = `buy-total`;
 //clears seller bio page which has active auctions listed

 console.log("Cannot delete buy now total")
 }
 })
 }
 //clears main page total count for pagination

 if (response == 1) {
 console.log("Deleted Listings Count Successfully!")
