## Motivation
<!--
Motivation Example
===
Our database is heavy on read operations than write operations. After users is growing, we need to optimize read performance to ensure low latency and high availability.
### Stackholder
- **Users**: Expect fast response times when accessing data.
- **Developers**: Need to maintain and scale the database efficiently.
### Problem Statement
The current database setup is struggling to handle the increasing read load, leading to slow response times and potential downtime during peak usage periods.

[DETAILED_DESCRIPTION_OF_THE_PROBLEM]
## Proposed Solution
<!--
Proposed Solution Example
===
We have considered the following solutions to address the read performance issue:
### Redis Caching
Implementing Redis as an in-memory caching layer to store frequently accessed data. This will reduce the load on the primary database and speed up read operations.
### Read Replicas
Setting up read replicas of the primary database to distribute read traffic. This will help in balancing the load and improving read performance.

Decision Example
===
After evaluating the proposed solutions, we have decided to implement Redis Caching because it provides a significant performance boost for read operations with relatively low complexity and cost.

## Consequences
<!--
Consequences Example
===
Implementing Redis Caching will have the following consequences:
### Positive Consequences
- Improved read performance, leading to faster response times for users.
- Reduced load on the primary database, enhancing overall system stability.
### Negative Consequences
- Additional infrastructure to manage and maintain (Redis server).
- Potential data consistency issues if cache is not properly invalidated.
