How to prevent stale data?
To avoid stale data, implement an appropriate cache locking strategy. By default, EclipseLink optimizes concurrency to minimize cache locking during read or write operations. Use the default EclipseLink isolation level, unless you have a very specific reason to change it.
What is flush cache?
When the amount of unwritten data in the cache reaches a certain level, the controller periodically writes cached data to a drive. This write process is called “flushing.” A high percentage setting limits the number of cache flushes so that more data remains in cache, which increases the chance of more cache hits.
How do you handle multiple users editing the same piece of data in a webapp?
Basically, you need to timestamp all your editable records with the last update time. When you try to save the record, you first verify that the record in the database has the same last-updated timestamp as your record.
Can I use stale-while-revalidate?
If the locally cached response is still fresh, then it can be used as-is to fulfill a browser’s request. From the perspective of stale-while-revalidate , there’s nothing to do in this scenario. If the age of a stale response falls into this window, then it will be used to fulfill the browser’s request.
How to handle multiple users editing the same piece of data?
The application should submit only the fields of the record that are changed. That way you prevent conflicts.
How to manage task list between multiple users?
There’s a project I’m working on that is looking to produce a web application that will manage a task list between multiple users. This is a master task list whose task items get distributed by an authorized user.
Which is the best way to scale your web application?
CloudFront can direct traffic to your on-premises or cloud-hosted server with its 113 Points of Presence (102 Edge Locations and 11 Regional Edge Caches) in 56 cities across 24 countries, which provides efficient caching. Step 2: Reduce read load by adding more read replicas. MySQL provides a nice mirror replication for databases.
