    [ https://issues.jboss.org/browse/ISPN-7991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428680#comment-13428680 ] 

Sebastian Łaskawiec commented on ISPN-7991:
-------------------------------------------

The current algorithm looks like the following: 

* We take the input data as bytes
* [We create metadata for it|https://github.com/infinispan/infinispan/blob/c8c632349a4899d8b6085329288f1615b0c2d33c/server/rest/src/main/java/org/infinispan/rest/operations/CacheOperations.java#L314], 
* [We store it in cache with metadata|https://github.com/infinispan/infinispan/blob/c8c632349a4899d8b6085329288f1615b0c2d33c/server/rest/src/main/java/org/infinispan/rest/operations/CacheOperations.java#L325]

By using metadata we know how to [convert it back]|https://github.com/infinispan/infinispan/blob/c8c632349a4899d8b6085329288f1615b0c2d33c/server/rest/src/main/java/org/infinispan/rest/operations/CacheOperations.java#L111-L112 when sending to the client. 

Now the biggest question that bothers me is what format needs to be used to make it working with compatibility? In case of String objects ({{content-type: text/plain}}), shall we put a String in cache? What about other types such as {{content-type: application/xml}}?

> Writing via Hot Rod and reading via Rest works fine, but not the other way around
