[infinispan-issues] [JBoss JIRA] (ISPN-2205) Design HotRod protocol version 1.2

[Mircea Markus (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12805523#comment-12805523 ] 

Mircea Markus commented on ISPN-2205:
-------------------------------------

[~galderz] There's still one thing to be addressed:
- the protocol defines the consistent hash (CH) in terms of wheels
- the server has a routing table
- we have some code on the server that builds/emulates the wheel in a way the client understands it

This hack has some drawbacks:
- in certain situations the primary owner computation on the client is not performed correctly (doesn't match the primary owner on the server)
- it is not efficient

We should improve the protocol to fix this.

> The consistent hash representation is changing in 5.2, and we need to modify the HotRod protocol to incorporate those changes. We preserved compatibility with 1.0/1.1 clients with a workaround on the server, but is not as efficient as it could be.
> The new version could also incorporate fixes for older issues like ISPN-1293.
