Local Email Archive Store for Faster Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing email archive systems face issues such as slow retrieval times for archived emails, limited user access when offline, and inadequate support for email features like previewing archived content, leading to a suboptimal user experience.
Innovation Solution
Implementing a local email archive store on the user's client computer that intercepts requests for archived emails, allowing for faster access and enabling features like displaying archived content in a preview pane, managing local archive store size, and updating email properties, while also backfilling the local store to improve performance and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If emails are archived on a remote server to reduce storage requirements, then storage efficiency is improved, but retrieval time increases and offline access becomes unavailable
Solution Approach 1:
The email storage system is segmented into two parts: a remote archive server for long-term storage and a local cache on the user's computer for frequently accessed emails. This segmentation allows emails to be distributed across different storage locations based on access patterns, reducing retrieval time for common emails while maintaining overall storage efficiency.
Solution Approach 2:
The system performs preliminary actions by automatically caching archived emails locally on the user's computer before they are needed. The email client monitors access patterns and pre-loads emails into the local cache, so when users need to retrieve archived emails, they are already available locally, eliminating retrieval delays.
2Quantity of substance
If emails are archived on a remote server, then storage requirements are reduced, but user access when offline is limited
Solution Approach 1:
The system segments email access into online and offline modes by maintaining a local cache of archived emails. When offline, users can access emails from the local cache without needing connection to the remote server, ensuring continuous availability and reliability of the email system regardless of network status.
Solution Approach 2:
The local cache acts as an intermediary between the user and the remote archive server. It stores copies of archived emails locally, allowing users to access their emails offline without direct interaction with the remote server. The local cache mediates between offline access requirements and remote storage, ensuring reliability while maintaining storage efficiency.
3Speed
If a local email archive store is implemented, then retrieval speed is improved, but storage requirements on the client computer increase
Solution Approach 1:
The system applies local quality by caching only the emails that are most likely to be accessed frequently, rather than storing all archived emails locally. The email client analyzes access patterns and stores copies of frequently accessed emails in the local cache, improving retrieval speed for these emails while minimizing the storage space required on the client computer.
Solution Approach 2:
The system changes parameters by dynamically adjusting the local cache size and email selection criteria based on available storage space and access patterns. When storage space is abundant, the cache can hold more emails; when space is limited, it prioritizes caching only the most frequently accessed emails, optimizing the balance between retrieval speed and storage requirements.
