Hi @khb. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Wasp itself does not have built-in multi-tenancy support, but it's possible to implement multi-tenancy in a Wasp application. Here are a few approaches you could consider: 1. Separate Databases: You could deploy multiple instances of your Wasp app, each with its own database for different tenants. This approach was discussed in a Discord thread where a community member suggested: Discord: Multi-tenancy with WASP and Postgres? "You could basically just deploy your app multiple times, each time with a different database." 2. Single Database with Tenant Isolation: A more common approach is to use a single database and ensure data isolation at the application level. As mentioned by a Wasp team member: "Typical approach is to have a single database and data from many users in it -> your server ensures everybody can access only their own data. That is industry standard, and more complicated solutions are used only when you have some special regulations, or are maybe deploying on prem or something." 3. Custom Implementation: You could implement a multi-tenant structure in your Prisma schema. A community member shared an example of a GitHub-like multi-tenant SaaS schema: Discord: Prisma schema for a github-like multi-tenant saas This schema includes features like individual user accounts, organization accounts, team support, and role-based access control. To implement multi-tenancy, you'd need to modify your Wasp app's data model, queries, and actions to include tenant-specific logic. The exact implementation would depend on your specific requirements and the level of isolation needed between tenants. It's worth noting that while Wasp doesn't have built-in multi-tenancy features, its flexibility allows you to implement such patterns using standard web development practices within the Wasp framework. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

@kapa.ai I would like to have one database that is multi-tenancy, however i also want multi-tenancy with the compute, so ill have a powerful machine running sumularion or caculating geometry, i want to be able to split the recorces up like cores or ram, is that possible?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- While Wasp itself doesn't provide built-in features for the specific multi-tenancy setup you're describing, especially regarding compute resource allocation, I can provide some general guidance based on the available information about Wasp and standard web application practices. 1. Database Multi-tenancy: As discussed in the previous answer, you can implement database multi-tenancy within a single database using Wasp. This typically involves adding a tenant identifier to your data models and ensuring proper data isolation at the application level. 2. Compute Resource Allocation: Regarding the allocation of compute resources like CPU cores or RAM for simulations or geometry calculations, this is not something that Wasp directly handles. Wasp is primarily focused on web application development and doesn't have built-in features for managing low-level system resources or distributed computing. To achieve what you're looking for, you might need to consider a hybrid approach: 1. Use Wasp for your web application's front-end and basic back-end operations. 2. Implement a separate service or microservice architecture for your resource-intensive computations. You could potentially use Wasp's API capabilities to interface with this separate computation service. As mentioned in this Discord thread: Discord: Running alongside separate authed API? You could set up your Wasp application to communicate with your separate computation service: "Wasp client <-> Wasp server <-> your existing data API server" This way, you can handle user authentication and basic operations in Wasp, while offloading the heavy computations to a separate service that you can scale and manage independently. However, the specifics of implementing resource allocation for simulations or geometry calculations are beyond the scope of what Wasp directly provides. You would need to implement this separately using appropriate technologies for distributed computing or high-performance computing, which are not covered in the provided Wasp documentation. For such a specialized setup, you might need to consider additional tools and technologies alongside Wasp to fully meet your requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

@kapa.ai sorry for my ignorance, but how do servers currently work, lets say i have lunched on fly.io, then i have 2 servers up 2 clients up and 1 database up. From my understanding everyone who connects to the website will hit one of the two clients, serving them with eberthing they need for the website, then when ever they do a calculation it run on the two servers, then gets passed to the database when done. Is this not already multi-tenancy? How it is curreclt working, because every clients data is on one database and everyone is useing the same servers for compute as it is.

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Your understanding is partially correct, but there are some important distinctions to make. Let's break down how the deployment on Fly.io typically works for a Wasp application and clarify the concept of multi-tenancy. When you deploy a Wasp application to Fly.io using the Wasp CLI, it creates three separate applications: 1. Client application (static files served by a web server) 2. Server application (your backend API) 3. Database (PostgreSQL) As mentioned in the Wasp documentation on Fly.io deployment: "The basename is used to create all three app tiers, resulting in three separate apps in your Fly dashboard: - my-wasp-app-client - my-wasp-app-server - my-wasp-app-db" Here's how it typically works: 1. Clients: These are not separate instances that users connect to directly. Instead, they are likely replicas of your static frontend files, distributed across Fly.io's global network for faster content delivery. 2. Servers: The two server instances you mentioned are likely replicas of your backend API. They handle requests from clients, process data, and communicate with the database. 3. Database: This is a single PostgreSQL instance that stores all your application data. This setup does provide some level of scalability and redundancy, but it's not inherently multi-tenant in the way that term is typically used in software architecture. True multi-tenancy usually refers to a software architecture where a single instance of the application serves multiple customers (tenants) while keeping their data isolated from each other. Each tenant's data is logically separated, even though it may be stored in the same database. In your current setup: 1. All users are interacting with the same application instance. 2. All data is stored in the same database without inherent logical separation between different customers or organizations. 3. The compute resources (your server instances) are shared among all users without specific allocation or isolation per tenant. To implement multi-tenancy, you would typically need to: 1. Modify your data model to include tenant identifiers. 2. Implement logic in your application to ensure data isolation between tenants. 3. Potentially set up resource quotas or limits per tenant. The current setup provides scalability and some level of redundancy, but it doesn't inherently provide the data isolation and resource allocation that are typically associated with multi-tenancy. To achieve true multi-tenancy, you would need to implement additional logic and structures within your application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

Can you give me a really basic example of both and the differences please. @kapa.ai

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Certainly! I'll provide a basic example of a non-multi-tenant setup and a multi-tenant setup, highlighting the key differences between them. 1. Non-Multi-Tenant Setup: In a basic non-multi-tenant Wasp application, you might have a simple user and post model:

model User {
  id    Int     @id @default(autoincrement())
  username String  @unique
  posts Post[]
}

model Post {
  id     Int    @id @default(autoincrement())
  title  String
  content String
  author User   @relation(fields: [authorId], references: [id])
  authorId Int
}

model User {
  id    Int     @id @default(autoincrement())
  username String  @unique
  posts Post[]
}

model Post {
  id     Int    @id @default(autoincrement())
  title  String
  content String
  author User   @relation(fields: [authorId], references: [id])
  authorId Int
}

In this setup: - All users and posts are stored in the same tables. - There's no inherent separation between data of different organizations or customers. - Any query for posts could potentially return posts from any user in the system. 2. Multi-Tenant Setup: In a multi-tenant version, you'd add a Tenant model and associate it with Users and Posts:

model Tenant {
  id    Int     @id @default(autoincrement())
  name  String
  users User[]
  posts Post[]
}

model User {
  id       Int     @id @default(autoincrement())
  username String  @unique
  tenant   Tenant  @relation(fields: [tenantId], references: [id])
  tenantId Int
  posts    Post[]
}

model Post {
  id       Int    @id @default(autoincrement())
  title    String
  content  String
  author   User   @relation(fields: [authorId], references: [id])
  authorId Int
  tenant   Tenant @relation(fields: [tenantId], references: [id])
  tenantId Int
}

model Tenant {
  id    Int     @id @default(autoincrement())
  name  String
  users User[]
  posts Post[]
}

model User {
  id       Int     @id @default(autoincrement())
  username String  @unique
  tenant   Tenant  @relation(fields: [tenantId], references: [id])
  tenantId Int
  posts    Post[]
}

model Post {
  id       Int    @id @default(autoincrement())
  title    String
  content  String
  author   User   @relation(fields: [authorId], references: [id])
  authorId Int
  tenant   Tenant @relation(fields: [tenantId], references: [id])
  tenantId Int
}

Key differences: 1. Data Isolation: Each user and post is associated with a specific tenant. This allows for easy filtering of data by tenant. 2. Query Modifications: In your Wasp operations (queries and actions), you'd need to always include the tenant ID. For example:

   const getPosts = query((args, context) => {
     const { tenantId } = context.user;
     return context.entities.Post.findMany({
       where: { tenantId: tenantId }
     });
   });

   const getPosts = query((args, context) => {
     const { tenantId } = context.user;
     return context.entities.Post.findMany({
       where: { tenantId: tenantId }
     });
   });

3. Resource Allocation: While not shown in the data model, you could add fields to the Tenant model to track resource usage or limits. 4. Authentication: Your authentication system would need to include the tenant information when creating tokens or sessions. The multi-tenant approach allows you to serve multiple organizations or customers from a single application instance and database, while keeping their data logically separated. This can lead to more efficient resource use and easier management, but requires careful implementation to ensure proper data isolation and security. Remember, this is a basic example and real-world multi-tenant systems often involve more complex considerations around security, scalability, and customization per tenant. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

@kapa.ai would it be possible to switch to mongo DB? On opensaas?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in the knowledge sources, it is currently not possible to switch to MongoDB for OpenSaaS or Wasp applications. Here's why: 1. Limited database support: Wasp currently only supports PostgreSQL and SQLite. As mentioned in the Github issue about expanding Prisma support, support for other databases like MongoDB is a potential future feature, but it's not implemented yet. 2. OpenSaaS requirements: The OpenSaaS template, which is built on Wasp, requires PostgreSQL for certain features. As stated in a Discord conversation: Discord: Mongodb with open-saas "Unfortunately we don't support mongodb for now! Prisma has support for it, so it is not super hard to support it and we might in the future, but we don't yet." 3. Wasp's current architecture: Some Wasp features, like Jobs, are specifically designed to work with PostgreSQL. Switching to MongoDB would require significant changes to the framework itself. While Prisma (the ORM used by Wasp) does support MongoDB, Wasp hasn't integrated this support into its framework yet. The Wasp team has acknowledged that supporting other databases, including MongoDB, is something they might consider in the future, but it's not currently available. If MongoDB support is crucial for your project, you might need to consider alternative solutions or wait for potential future updates to Wasp and OpenSaaS that might include MongoDB support. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

Can i use opensaas for a micro services? @kapa.ai Can i use opensaas for a micro services?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in the knowledge sources, OpenSaaS and Wasp are not specifically designed for building microservices architectures. OpenSaaS is a SaaS boilerplate template built with Wasp, which is primarily focused on creating full-stack web applications using React, Node.js, and Prisma. However, while OpenSaaS itself isn't designed for microservices, you could potentially use it as part of a larger microservices architecture. Here are a few points to consider: 1. API Integration: Wasp allows you to create APIs that could be consumed by other services. As mentioned in a Discord thread: Discord: Running alongside separate authed API? You could set up your Wasp application to communicate with other services: "Wasp client <-> Wasp server <-> your existing data API server" 2. Monolithic Structure: OpenSaaS and Wasp are designed more as monolithic applications rather than microservices. They provide a full-stack solution with tightly integrated frontend and backend. 3. Database Limitations: OpenSaaS uses PostgreSQL, which might limit your ability to create truly independent microservices if they all need to share the same database. 4. Deployment: While Wasp provides deployment options to platforms like Fly.io, it's not specifically optimized for deploying and managing multiple independent microservices. If you're looking to build a microservices architecture, you might need to consider using OpenSaaS or Wasp for a specific service within your architecture rather than as the foundation for the entire microservices system. Alternatively, you might need to look into other frameworks or tools that are more specifically designed for microservices architectures. Remember, the choice between a monolithic architecture (which OpenSaaS leans towards) and a microservices architecture depends on your specific project requirements, scale, and complexity. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.

What if i had open saas as like the landing page and databade, then had api for the complex calculations. Then had the api send back to the database, would that take to long. @kapa.ai What if i had open saas as like the landing page and databade, then had api for the complex calculations.

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in the knowledge sources and our previous conversation, your proposed architecture could potentially work with OpenSaaS and Wasp. Let's break down your idea and discuss its feasibility: 1. Using OpenSaaS for landing page and database: This is perfectly aligned with OpenSaaS's strengths. It can handle the frontend (landing page) and manage the database effectively. 2. Separate API for complex calculations: This approach is similar to what was discussed in the Discord thread about running alongside a separate authenticated API. As mentioned: Discord: Running alongside separate authed API? You could set up a structure like: "Wasp client <-> Wasp server <-> your existing data API server" In your case, the "existing data API server" would be your service for complex calculations. 3. API sending results back to the database: This is feasible. Your calculation API could send results back to the Wasp server, which would then update the database. Regarding your concern about the time this might take, it's important to note: 1. Performance depends on various factors such as the complexity of calculations, network latency, and database write speed. 2. If the calculations are truly complex and time-consuming, you might want to consider implementing asynchronous processing. Wasp supports background jobs, which could be useful here. As mentioned in the Wasp documentation: Wasp Docs: Recurring Jobs "What if the server needs extra time to fully process the request? This might mean sending an email or making a slow HTTP request to an external API. In that case, it's a good idea to respond to the user as soon as possible and do the remaining work in the background." 3. You could implement a system where the calculation is initiated, and the user is notified when it's complete, rather than waiting for the entire process to finish before responding. To optimize this setup: 1. Ensure your API for complex calculations is efficient and well-optimized. 2. Consider using Wasp's job system for managing long-running tasks. 3. Implement proper error handling and retry mechanisms for robustness. 4. Use appropriate caching strategies where possible to reduce unnecessary calculations or database queries. While this architecture can work, the specific performance characteristics would depend on your implementation details and the nature of your calculations. It would be advisable to build a prototype and conduct performance testing to ensure it meets your requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ---------------------- Sorry @khb, I seem to be having a bit of trouble.
