Session Data Persistence Task

A Session Data Persistence Task is a data persistence task that saves user session states from session memory to persistent session storage maintaining session continuity across server restarts and load balancers.

• AKA: Session Saving Task, Session State Persistence, Session Storage Operation.
• Context:
  • It can typically store Session Variables including user context.
  • It can typically save Authentication Tokens for login state.
  • It can typically maintain Shopping Cart State during browsing sessions.
  • It can typically preserve Form Input Data across page navigation.
  • It can typically track Session Activity for user analytics.
  • ...
  • It can often implement Session Replication across server clusters.
  • It can often expire Stale Sessions for resource management.
  • It can often compress Session Objects for memory efficiency.
  • It can often encrypt Session Cookies for security protection.
  • ...
  • It can range from being a Server-Side Session Persistence Task to being a Client-Side Session Persistence Task, depending on its storage location.
  • It can range from being a Short-Lived Session Persistence Task to being a Long-Lived Session Persistence Task, depending on its retention duration.
  • ...
  • It can utilize Redis Session Stores for fast access.
  • It can employ Database Session Tables for reliable storage.
  • It can leverage Distributed Caches for scalable persistence.
  • ...
• Example(s):
  • Web Application Session Persistences, such as:
    • E-commerce Session Persistence Task maintaining cart items.
    • Banking Session Persistence Task securing transaction state.
    • Gaming Session Persistence Task saving game progress.
  • Authentication Session Persistences, such as:
    • SSO Session Persistence Task for single sign-on.
    • OAuth Session Persistence Task storing access tokens.
    • SAML Session Persistence Task maintaining assertion data.
  • Application State Persistences, such as:
    • Workflow Session Persistence Task tracking process state.
    • Chat Session Persistence Task preserving conversation context.
    • Search Session Persistence Task maintaining filter selections.
  • ...
• Counter-Example(s):
  • Stateless Session Management, which avoids session persistence.
  • JWT Token Authentication, which embeds session data in token payload.
  • Cookie-Only Storage, which limits to client-side persistence.
