Title: Enhance Query Performance in Storage API

Author: Alice Johnson

Date: October 20, 2023

Link: [GitHub PR Link]


Overview: This PR enhances the query performance of the Thanos storage API by implementing caching mechanisms for frequently accessed data.

Changes Introduced:

  • Added an in-memory caching layer to reduce repeated storage queries.
  • Refactored query handling to better leverage the caching system.
  • Updated API documentation to reflect the caching behavior.

Motivation: The changes were prompted by user feedback indicating performance bottlenecks during high-load scenarios. This PR aims to address issue #1234.

Testing: Comprehensive unit tests have been added to validate the caching logic. Performance benchmarks were conducted, demonstrating a 30% reduction in query time.

Impact: The new caching layer is expected to significantly improve the user experience during heavy usage. There are no breaking changes, and it remains backward compatible.

Review Notes: Special attention is required for the eviction strategy used in the cache implementation to ensure it meets the expected performance metrics.

Dependencies: This PR relies on the ongoing work in PR #5678 for the new storage interface.
