If by Style, you mean the formatting? then I think so. If by style you mean interfaces and class design, Till and I have been discussing going over the interfaces at some point. For now, this is correct and it means that you give this converter a DCPRequest (DCPRequest id a dcp message. I don't know why they named the class DCPRequest and I brought it up with them). The char[] means that the returned record object has a char[] which can be parsed. Line 116: bytes.compact(); > A lot of memory copies here? the SDK use netty byte buffer which id different from java ByteBuffer. the decoder only deals with ByteBuffers and CharBuffer. The parser can only deal with char[]. hence, doing all of this data movement. For now, I think this is okay. At least, I am not creating any objects and all the copying is bulk operations which are relatively cheaper. -- To view, visit https://asterix-gerrit.ics.uci.edu/951 To unsubscribe, visit https://asterix-gerrit.ics.uci.edu/settings Gerrit-MessageType: comment Gerrit-Change-Id: I71c3d8b8dfa5a98123725f139247d2b5ce10012e Gerrit-PatchSet: 2 Gerrit-Project: asterixdb Gerrit-Branch: master Gerrit-Owner: abdullah alamoudi <bamou...@gmail.com> Gerrit-Reviewer: Jenkins <jenk...@fulliautomatix.ics.uci.edu> Gerrit-Reviewer: Yingyi Bu <buyin...@gmail.com> Gerrit-Reviewer: abdullah alamoudi <bamou...@gmail.com> Gerrit-HasComments: Yes
