[ https://issues.apache.org/jira/browse/IGNITE-12831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=17067436#comment-17067436 ] Ilya Shishkov commented on IGNITE-12831: [~antonovsergey93], [~ktkale...@gridgain.com], as I see, you are right, local caches has cluster-wide behaviour, and created and destroyed on all nodes. But from the point of ordinary Apache Ignite user, the above phrase very implicitly tells us about behaviour of create and destroy procedures. So, IMHO, we should add to documentation some warnings about add/destroy, and about that fact, that local caches are deprecated and will be removed from Apache Ignite 3.0 and are strictly 'not recommended' for use in production. > Invoking destroy of local cache on one node destroys local caches with the > same name on all other nodes > --- > > Key: IGNITE-12831 > URL: https://issues.apache.org/jira/browse/IGNITE-12831 > Project: Ignite > Issue Type: Bug > Components: cache >Affects Versions: 2.8, 2.7.6 >Reporter: Ilya Shishkov >Priority: Major > Attachments: MyLocalCacheDestroyReproducer.java > > > If you create caches with cache mode CacheMode.LOCAL and same name, but on > different nodes, then all those caches will be destroyed after invoking > destroy of cache on one of the cluster nodes. > Expected behaviour: local cache should be destroyed only on the node invoking > destroy. > Reproducer in attachment. -- This message was sent by Atlassian Jira (v8.3.4#803005)

{quote}Expected behaviour: local cache should be destroyed only on the node
invoking destroy.{quote}
Your expectation is not valid. Look at the documentation [1]:
LOCAL mode is the most light weight mode of cache operation, as no data is
distributed to other cache nodes. It is ideal for scenarios where data is
either read-only, or can be periodically refreshed at some expiration
frequency. It also works very well with read-through behavior where data is
loaded from persistent storage on misses.* Other than distribution, local
caches still have all the features of a distributed cache, such as automatic
data eviction, expiration, disk swapping, data querying, and transactions.*
If you want to change that behavior please start a discussion on the dev list.
