Query Caching Redis Module

Redis Query Caching Module Summary

This Redis module implements a custom query caching mechanism. It allows users to store and retrieve the results of expensive queries using Redis as a high-performance, in-memory cache. The module includes:

Custom Query Commands: A set of commands to execute, store, and retrieve cached queries.

Expiration Management: Cached entries automatically expire after a configurable duration to prevent stale data.

Extendable Expiration: A dedicated command supports extending the expiration time of selected queries by passing a list of query identifiers, improving control over cache retention.

Efficient Storage: Results are stored with keys derived from a hash of the query string, ensuring uniqueness and consistency.

Performance Optimization: Designed to reduce back-end load and improve response times for repeated queries.

The module is ideal for scenarios where query results are expensive to compute and are frequently requested.
