Cache Item Invalidation

[Marty Jones <ma...@gmail.com>]

How do you guys handle invalidating cache items when the underlying data is
changed within say a database you are using to create cache items with?

For external events, you would need to monitor those events and expiry
manually.
Ignite does have notification capabilities int the form of events for cache
put/get and other operations
see here: https://apacheignite.readme.io/docs/events
You can use that

example:

I understand the expiration policies but my question is about automatically
expiring a cache entry when an external event occurs such as a database
table column changes.
