MariaDB

Hello,

I'm in the midst of reviewing an old CRUD SAAS I have running on Angular 7 with a MariaDB backend and Laravel PHP. Presently is hosted on a couple of Linode servers- and really feeling the weight, especially with the looming need to upgrade to A15 and meet the pace and scalability occurring (for context, the SAAS turns in over 24k USD monthly in subscriptions- so I have concerns around the impact of a new stack on existing clients). Additionally, I manage a Kotlin and Swift codebase for appdev.

I'm looking at moving towards Flutter for a singular codebase, and something serverless but still relational- like Supabase. In the past, I ran my own Auth services- but it was a ton of work to setup and maintain, so looking at using Firebase for Auth services (I know Supabase has Auth as well, but I wonder if it's as reliable and frequently maintained as Firebase?) Supabase has a FlutterSDK as well which makes things much simpler. Planning on maintaining microservices like Stripe etc for functional aspects.

I would love some insight from those who have done a tech stack transition, what should I be aware of- those who have produced in Flutter or a similar stack, what am I walking into without knowing?

I need advice. Am currently building a real estate marketplace mobile app using Flutter for frontend. I am not sure which backend solution to use, and thinking of using Firebase, Django or Laravel for backend and MongoDB/MariaDB for the database. I want to build an API backend and then use RESTful API calls for the frontend.

I'm a SQL Server person and researching which tool is more like SSMS for use with MariaDB? Thank!

I have a lot of data that's currently sitting in a MariaDB database, a lot of tables that weigh 200gb with indexes. Most of the large tables have a date column which is always filtered, but there are usually 4-6 additional columns that are filtered and used for statistics. I'm trying to figure out the best tool for storing and analyzing large amounts of data. Preferably self-hosted or a cheap solution. The current problem I'm running into is speed. Even with pretty good indexes, if I'm trying to load a large dataset, it's pretty slow.

We use AppOptics. I am curious what are the current leaders for APM for small companies (50 employees) that use Python, MariaDB, RabbitMQ, and Google Cloud Storage. We run both Celery and Gunicorn services. We are considering Datadog or some other deep code profiling tool that can spot I/O, DB, or other response time/request rate issues

I'm researching what Technology Stack I should use to build my product (something like food delivery App) for Web, iOS, and Android Apps. Please advise which technologies you would recommend from a Scalability, Reliability, Cost, and Efficiency standpoint for a start-up. Here are the technologies I came up with, feel free to suggest any new technology even it's not in the list below.

For Mobile Apps -

1. native languages like Swift for IOS and Java/Kotlin for Android
2. or cross-platform languages like React Native for both IOS and Android Apps

For UI -

1. React

For Back-End or APIs -

1. Node.js
2. PHP

For Database -

1. PostgreSQL
2. MySQL
3. Cloud Firestore
4. MariaDB

Thanks!
