DEV Community: Oleg Khorev

Another day :) Another code... I like my work :) What I got from my 21 years experience in web-dev - all language variables must be readable English words. Next all code will be written on the fly, without any thoughts. Strict variables names-standards :)

MySQL index or Manticore Search?

Oleg Khorev — Sun, 13 Sep 2026 14:34:29 +0000

I had read on Claude that if you optimize MySQL table to 100kk rows, it will work same quick for 100kkk rows too.

I am not sure. I cannot load Manticore Search with 100kkk rows, lol :)

However I tested Manticore Search with 20kk rows and search text in it and 20 queries in the same function work in 100-200ms.

Good question. Hope one day I will get that experience(these knowledges) and compare :)

If you are an old developer

If you are an old developer and have dream to learn something or build something - you can consider my SPA-Cart.

It is built with jQuery/PHP/MySQL.

Code structure is very simple:

index.php
Includes
Pages
Templates

Templates engine is similar to Smarty but much more developer friendly.

More about it you can find here:
https://spa-cart.com/page/about_spa_cart.html

Free download:
https://spa-cart.com/page/spa-cart-download.html

Demo:
https://demo.spa-cart.com/
https://demoadmin.spa-cart.com/admin

I finally opened this CMS to world. Hope no bugs or errors. I will try to not touch it for any version upgrades. All looks stable. Only high level security issues I will fix.

New version has a few medium security issues in Google - but it was just because Admin area was on the same domain as Customer area.

Does it worth to use end-to-end or just regular encryption in new startups? I think it's a future. Google AI can tell every function how to make it. Key for user, or per chat. Key maybe on server or some way on user's PC. What do you think?

Submit your site to global catalogs

Oleg Khorev — Thu, 10 Sep 2026 19:33:31 +0000

Today I found the great site. It allows to submit your startup or already established business to many catalogs.

Just follow this URL
https://www.saashub.com/services/submit

Enter Website URL and you will get many free and paid sites/services where you can just very easy submit your product.

I submited my SPA-Cart to many catalogs. They have a lot of traffic. Or if you have budget - you can even pay and submit more :)

Good luck with your marketing.

My SPA-Cart site perfomance

After some long way, finally my SPA-Cart score is fantastic on PageInsights

Oh. Very sad experience with Codester again :( I don't know why they are so strict. Why my SPA-Cart was rejected. Why they not restorting my forum account after I begged them. Why they have no human's feelings. They are more strict than a machine ;(

My sites were spamming by Singapore. I blocked all recorded IPs submasks

Elastic Search or Manticore Search?

Oleg Khorev — Tue, 08 Sep 2026 07:43:01 +0000

What do you think? Elastic Search has 2kkk records on one server. Manticore Search has tens of billions of records. I did not test Elastic Search, but Manticore Search works very quick.

I loaded database with 20kk records. Each page load queries 20-30 times the 20kk table. There are even text searches. It works in 100-200ms. Enough to get grown and share database between Shards.

Good morning :) Was sleeping very bad recently. I sleep 10-11 hours a day usually and getting restored for code. I keep so many information in my head :) My 21 years of web-dev experience made a lot of knowledges and experience. Again a lot of energy :)
