[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1090) Hot Rod protocol improvements for version 2

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12600722#comment-12600722 ] 

Galder Zamarreño commented on ISPN-1090:
----------------------------------------

Well, for an L1 in clients you need listeners so that you can be notified when things change on the server side. I think this is important, particularly cos a lot of people using Coherence like the L1 capabilities that they bring. Anyway, the L1 and event listeners is already covered in a separate JIRA. This jira is more geared towards having:

- Small improvements that do not need a separate jira
- Link to bigger jiras such as ISPN-484 or ISPN-374.

The custom commands could be interesting but I'd like to see concrete use cases for this.

> This JIRA will act as a place to keep track of enhancements to the Hot Rod protocol that should be included in version 2 of the protocol:
> - We need a new error status code so that clients can detect when a node has been suspected and so react accordingly (i.e. not bubble it up but instead failover). Currently, this can be solved by checking whether the error message contains SuspectException but this is not nice.
> - Since we're not gonna be supporting asymmetric clusters in the mean time, we need a new error status code to deal with situations where the cache is not defined in the server. Currently we check for CacheNotFoundException in the message but that's not nice.
