             Summary: Avoid blocking on CacheInputStream
                 Key: ISPN-10661
                 URL: https://issues.jboss.org/browse/ISPN-10661
             Project: Infinispan
          Issue Type: Enhancement
          Components: REST
            Reporter: Gustavo Fernandes
            Assignee: Gustavo Fernandes


As part of ISPN-10376, the REST server is serving keys using Netty's {{ChunkedWriteHandler}} that will convert a InputStream into chunks and will write it to the client. 

As the source of the InputStream is a CacheStream, that can block, it's desirable to do the retrieval of the cache data in a separate thread, using the suspend and resume capabilities of the {{ChunkedWriteHandler}} when data is available
