Is there a way to persist data in EhCache 3+ during restarts?

[Khaled]

Hi,

I would like to check if EhCache 3+ supports persisting data from cache before application restart?

I see something related for EhCache 2.7: http://www.ehcache.org/documentation/2.7/configuration/fast-restart.html

Any information for EhCache 3? Thank you.

1. What version of Ehcache you are currently using;   
   3.4.0
2. Paste the configuration for the Cache/CacheManager you have an issue with;
   Using CacheConfiguration and CacheManagerBuilder via code to construct a Cache instance with on-heap + off-heap storage

1. Add any name and version of other library or framework you use Ehcache with (e.g. Hibernate);
   None
2. Providing JDK and OS versions maybe useful as well.
   Java 8

Yes. It does.

When using disk persistence. Here: http://www.ehcache.org/documentation/3.5/tiering.html#disk-tier

However, the server must do a clean shutdown. Fast restart in case of failure is currently an enterprise feature.

Hi Henri,

Thanks a lot for your help.

A small follow up question: does this only persist disk level resource pool tier ? 

I am currently using on-heap and off-heap tiers. Do I need to add disk tier for persistence to work? 

Thanks in advance

Hello,

No, it will persist all the entries; ehcache 3 being a multi tiered caching library and the different tiers being part of a hierarchy, if you set up on heap + offheap + disk, disk will be the authoritative tier and as such will contain all your entries,

See  http://www.ehcache.org/documentation/3.5/tiering.html

Just to confirm though… you will need to add a disk tier.
