Use chunked reads/writes in TcpTransport ---------------------------------------- Key: ISPN-7802 URL: https://issues.jboss.org/browse/ISPN-7802 Project: Infinispan Issue Type: Bug Components: Remote Protocols Affects Versions: 9.0.0.Final Reporter: Radim Vansa Assignee: Tristan Tarrant Fix For: 9.1.0.Final, 9.1.0.Alpha1 The buffering implementation of {{TcpTransport.socketInputStream}} needs to use fixed size input buffer, rather than growing as {{BufferedInputStream}} does. Growing buffer can lead to excessive memory consumption on heap, and more importantly, by direct memory allocated in JDK classes and pooled in thread-local caches. EDIT: As Tristan pointed out, the {{BufferedInputStream}} does not grow in our use case, but if {{TcpTransport}} passes a big {{byte[]}} buffer, the implementation works as read through/write through. Therefore we need to chunk all calls.
