Galder Zamarreño updated ISPN-5077:
-----------------------------------
Fix Version/s: 9.4.0.Final
(was: 9.3.0.Final)
Custom remote events can be slightly inefficient
------------------------------------------------
Key: ISPN-5077
URL:
https://issues.jboss.org/browse/ISPN-5077
Project: Infinispan
Issue Type: Enhancement
Components: Remote Protocols
Affects Versions: 7.0.2.Final
Reporter: Galder Zamarreño
Fix For: 9.4.0.Final
Something we might want to improve for Hot Rod 3.0 protocol:
[16:40] <galderz> i've been thinking further about converters, and I think
i've found a slight mismatch between what converter means for embedded listeners vs
remote listeners
[16:40] <wburns> oh yeah?
[16:40] <galderz> for embedded listeners, it essentially transforms what you see
as `value`
[16:41] <galderz> with the knowledge that key and metadata information will be
shipped
[16:41] <galderz> the way i mapped converter to remote listeners is that whatever
the converter returns, we ship that, as is, to the client
[16:41] <galderz> so, if a remote listener wants a custom event that includes key
+ value
[16:41] <galderz> it needs to develop a converter impl that returns bytes
containing key + value
[16:41] <galderz> which is inefficient because you are passing around the key
twice
[16:42] <galderz> once as part of the event itself, and again inside the converted
value
[16:42] <galderz> inefficient from the POV of shipping stuff around from other
nodes to where the cluster listener is located
[16:44] <wburns> yeah makes sense
[16:44] <galderz> not a major issue but not easy to fix without changing semantics
or public protocol
