[JBoss JIRA] (ISPN-6279) Refactor CacheLoader API to make it thread safe

by Sebastian Łaskawiec (JIRA)

[ https://issues.jboss.org/browse/ISPN-6279?page=com.atlassian.jira.plugin.... ] Sebastian Łaskawiec commented on ISPN-6279: ------------------------------------------- After thinking about it a little bit longer, I think it would be good to have a default implementation of {{process}} method (which as you mentioned could use {{WithinThreadExecutor}}). This method could call our new simplified method (without {{Executor}} argument etc). This way less advanced users could use simplified API (and be less exposed to concurrency issues in their own code) whereas more advanced could implement {{process}} and do whatever they like. [~william.burns] WDYT? > Refactor CacheLoader API to make it thread safe > ----------------------------------------------- > > Key: ISPN-6279 > URL: https://issues.jboss.org/browse/ISPN-6279 > Project: Infinispan > Issue Type: Feature Request > Components: Loaders and Stores > Reporter: Sebastian Łaskawiec > Priority: Minor > Fix For: 9.0.0.Final > > > h3. Introduction > Currently {{CacheLoader}} thread safety can be easily compromised by broken implementations. We should provide a better implementation to make it more convenient and less error prone. > h3. Problem statement > CacheLoader API looks like this: > {code} > public interface AdvancedCacheLoader<K, V> extends CacheLoader<K, V> { > ... > void process(KeyFilter<? super K> filter, CacheLoaderTask<K, V> task, Executor executor, boolean fetchValue, boolean fetchMetadata); > ... > } > {code} > The CacheLoader implementation controls {{CacheLoaderTask}} as well as the number of threads used for processing (specified by {{Executor}}). If one wants to collect all keys (similarly to [AdvancedCacheLoader|https://github.com/infinispan/infinispan/blob/master/...]) it is very easy to hit concurrently issues while adding them to the set (See previous JIRAs: ISPN-3938 and ISPN-6276). > h3. Solution > The solution should take away currently control (Executor) and keyset (the simplest idea is to add it to {{CacheLoaderTask}}) from from the implementation. One of the ideas is to create a Lambda expression for pulling records from Cache Store. Note that similar changes will need to be performed to {{CacheWriter}} (to make it similar). -- This message was sent by Atlassian JIRA (v6.4.11#64026)

[JBoss JIRA] (ISPN-6298) Network partition detection not working in mgmt console

by Jiří Holuša (JIRA)

[ https://issues.jboss.org/browse/ISPN-6298?page=com.atlassian.jira.plugin.... ] Jiří Holuša updated ISPN-6298: ------------------------------ Description: Page: Clusters -> select server group. When I create a network partition and go to the page above, I still see the cluster status as "started". According to https://issues.jboss.org/browse/ISPN-5768 , there should be something as "Degraded" I checked that the cluster is really partitioned. When I go to JConsole, I see in JGroups JChannel attributes, that the "view" is only partial. I also see in the server logs that servers correctly detected the split. When I go to homepage (or the "Status event" tab), I see in the "Latest Grid Events:" that the split happened, hence the mgmt console is able to correctly detect it elsewhere. Note that neither the status of a cache, which has configured partition handling to true, changes. was: Page: Clusters -> select server group.
