Optimizing database queries

Oct 13, 2025 by wbrum.org 14 views

Overview

In this feature, we will be reorganizing the request for customer reviews by utilizing the query property. This change aims to improve the overall structure and efficiency of the request, while also adhering to best practices for API design. Additionally, we will be avoiding the use of order in the CustomerReviewForBE model and creating a mediator service to facilitate the request.

Problem Statement

The current implementation of the customer review request is not optimized for performance and scalability. The use of order in the CustomerReviewForBE model can lead to inefficient database queries and slow response times. Furthermore, the request structure is not flexible enough to accommodate different use cases and requirements.

Solution

To address these issues, we will be implementing the following changes:

1. Reorganize the Request via `query` Property

We will be utilizing the query property to reorganize the request for customer reviews. This will allow us to pass parameters and filters in a more flexible and efficient manner.

Benefits of Using query Property

Improved Performance: By using the query property, we can reduce the number of database queries and improve response times.
Increased Flexibility: The query property allows us to pass parameters and filters in a more flexible and efficient manner, making it easier to accommodate different use cases and requirements.
Better Scalability: The query property enables us to handle large volumes of data and complex queries more efficiently.

2. Avoid `order` in CustomerReviewForBE

We will be avoiding the use of order in the CustomerReviewForBE model to improve the efficiency of database queries and reduce response times.

Benefits of Avoiding order

Improved Performance: By avoiding the use of order, we can reduce the complexity of database queries and improve response times.
Increased Flexibility: Without the order property, we can more easily accommodate different use cases and requirements.
Better Scalability: Avoiding the use of order enables us to handle large volumes of data and complex queries more efficiently.

3. Create a Mediator Service

We will be creating a mediator service to facilitate the request and improve the overall structure and efficiency of the request.

Benefits of Mediator Service

Improved Structure: The mediator service will help to improve the overall structure and organization of the request.
Increased Efficiency: The mediator service will enable us to handle complex queries and large volumes of data more efficiently.
Better Scalability: The mediator service will improve the scalability of the request and enable us to handle a large number of requests.

Implementation

To implement these changes, we will be following these steps:

1. Update the Request Structure

We will be updating the request structure to utilize the query property and avoid the use of order.

Updated Request Structure

{
  "query": {
    "filter": {
      "field": "value"
    },
    "sort": {
      "field": "value"
    }
  }
}

2. Create the Mediator Service

We will be creating a mediator service to facilitate the request and improve the overall structure and efficiency of the request.

Mediator Service

import { Injectable } from '@nestjs/common';
import { CustomerReviewForBE } from './customer-review-for-be.model';

@Injectable()
export class CustomerReviewMediatorService {
  async getCustomerReviews(query: any): Promise<CustomerReviewForBE[]> {
    // Implement the logic to retrieve customer reviews based on the query
  }
}

3. Update the Controller

We will be updating the controller to utilize the mediator service and improve the overall structure and efficiency of the request.

Updated Controller

import { Controller, Get, Query } from '@nestjs/common';
import { CustomerReviewMediatorService } from './customer-review-mediator.service';

@Controller('customer-reviews')
export class CustomerReviewController {
  constructor(private readonly customerReviewMediatorService: CustomerReviewMediatorService) {}

  @Get()
  async getCustomerReviews(@Query() query: any): Promise<CustomerReviewForBE[]> {
    return this.customerReviewMediatorService.getCustomerReviews(query);
  }
}

Conclusion

In this feature, we have reorganized the request for customer reviews by utilizing the query property and avoiding the use of order in the CustomerReviewForBE model. We have also created a mediator service to facilitate the request and improve the overall structure and efficiency of the request. These changes will improve the performance, scalability, and flexibility of the request, making it more efficient and effective.

Future Work

In the future, we can further improve the request structure and efficiency by:

Implementing caching: Implementing caching will enable us to reduce the number of database queries and improve response times.
Optimizing database queries: Optimizing database queries will enable us to improve the performance and scalability of the request.
Implementing pagination: Implementing pagination will enable us to handle large volumes of data and complex queries more efficiently.
