Enable User Marshaller Configuration

[eitch]

I have the same problem. Or how can i configure an instance to marshall my objects? I can create a cache remotely, but i can't have it store my objects.

@eitch To clarify, are you trying to create a remote cache which store's keys and/or values as application/x-java-object?

If no processing of the objects is required on the server side, it's possible to simply use the marshaller on the client and store the marshalled values on the server.

Hi @ryanemerson

I read in a tutorial, can't find it write now, that i could perform streams with filtering and that the filters would be serialized to the cluster nodes, and that i thus could use the compute power of the nodes and not have to transfer all the data to the server performing the query. Or did i misunderstand something?

This is why i want to store my objects as Java objects, and not marshall them.

Of how would i go about this? My idea is to start a cluster of infinispan nodes for storage, then connect remotely with a hotrod client and be able to use the remote nodes as cache, but also use their resources for filtering when searching for objects. Otherwise i would need to implement an index feature in my app and then only retrieve the items i really need. Is this possible?

@eitch For your use-case, utilising remote querying should provide what you require without having to make any changes to the server (image) config.

https://infinispan.org/docs/stable/titles/developing/developing.html#query_remote

The use of .proto files means that querying can be achieved without having to store your objects as POJOs on the server, which has the advantage of normal cache operations being faster, as each GET/PUT etc does not have to remarshall the stored key/value when responding to the client.

[eitch]

That is an idea, but i would prefer to not reimplement my searching logic, as it builds up on Streams, and unless i misunderstood it, Infinispan explicitly supports serializing Stream filters, or not?

[ryanemerson]

For now the only way to configure a serialization based marshaller with the image, is to supply a custom xml config as described here that has the required marshaller configured.

[eitch]

ahh, yes, i saw that, and i was going to use it, but then i saw that the XML file needs to have the correct IP etc. all configured, which the previous image would have handled. I guess i need to build my image on top which set the variables...

[ryanemerson]

@eitch If you pass -b SITE_LOCAL when launching the server you shouldn't need to hardcode the IP. If you utilise a custom jgroups stack, make sure that the transport protocol has the following:

bind_addr="${jgroups.bind.address,jgroups.udp.address:SITE_LOCAL}"        bind_port="${jgroups.bind.port,jgroups.udp.port:0}"

And the variables will be replaced as required.

Closing. The config-generator has been deprecated since 13.x. Users should provide their required server configuration directly to the image: https://github.com/infinispan/infinispan-images#server-configuration
