(/) {color:green}+1 client integration test{color} > Reduce memory copying in Rest server when serializing CellModel to Protobuf > --------------------------------------------------------------------------- > > Key: HBASE-28556 > URL: https://issues.apache.org/jira/browse/HBASE-28556 > Project: HBase > Issue Type: Improvement > Components: REST > Reporter: Istvan Toth > Assignee: Istvan Toth > Priority: Minor > Labels: pull-request-available > Fix For: 2.4.18, 3.0.0, 2.7.0, 2.6.1, 2.5.9 > > > The REST server does a lot of unneccessary coping, which could be avoided at > least for protobuf encoding. > - -It uses ByteStringer to handle ByteBuffer backed Cells. However, it uses > the client API, so it should never encounter ByteBuffer backed cells.- > - It clones everything from the cells (sometimes multiple times) before > serializing to protbuf. > We could mimic the structure in Cell, with array, offset and length for each > field, in CellModel and use the appropriate protobuf setters to avoid the > extra copies. > There may or may not be a way to do the same for JSON and XML via jax-rs, I > don't know the frameworks well enough to tell, but if not, we could just do > the copying in the getters for them, which would not make things worse. -- This message was sent by Atlassian Jira (v8.20.10#820010)
