How to evict cache in Embedded topology?

[skaaa...@gmail.com]

Hi,

I have setup Hazelcast embedded topology and each of node have REST api to evict the cache.

I'm currently stuck on building Evict all cache button which will evict all cache from all member in cluster.

Question is, Do I have to call to my REST api to evict cache in each and every node in cluster when user click on button? or have better solution to evict all caches.

Thank in advanced!

I'm not sure about the REST interface, I never tried it to do something with maps. But when evict invoked on a map from any node it causes the whole map eviction. Hope the same is true when it is done via REST.

HTH, Denis.

Starting with Hazelcast 3.7, Hazelcast Map uses a new eviction mechanism which is based on the sampling of entries.

please see the following updated documenation: http://docs.hazelcast.org/docs/3.8.2/manual/html-single/index.html#eviction-algorithm 

The resulting eviction is the same regardless of API invocation / java/rest/jmx

Hi Korrawit,

Normally, calling IMap#evictAll from a single node should be sufficient to evict all items from IMap. No need to call it from all nodes.
