Description

I would like to know for possible solutions for invalidation of cached tiles. When I update any feature in my DB, it doesn't reflect on UI, even after refresh on UI.

My setup UI <-> MARTIN <-> POSTGIS

1 solution is setting cache_size to 0, but that impacts performance badly.

Contributor guide

Research direction
Investigate the current caching mechanism in MARTIN, identify where and how tiles are cached, and propose strategies for cache invalidation (e.g., TTL, event driven invalidation via database triggers, or using a cache busting key). Consider trade offs between performance and freshness.
