Stephan Ewen commented on FLINK-3387: ------------------------------------- Nice, thanks for helping out with this. I would start with replacing the deserialization from {{byte[]}} with {{DataInputDeserializer}}. There should be only one instance of the {{DataInputDeserializer}}, which is always reused by {{deserializer.setBuffer(bytes, 0, bytes.length)}}. > Replace all ByteArrayOutputStream and DataOutputStream use in State Backends > by DataOutputSerializer > ---------------------------------------------------------------------------------------------------- > > Key: FLINK-3387 > URL: https://issues.apache.org/jira/browse/FLINK-3387 > Project: Flink > Issue Type: Bug > Components: state backends > Affects Versions: 1.0.0 > Reporter: Stephan Ewen > Assignee: Subhobrata Dey > > Currently, the {{byte[]}} to object conversion and vice versa is always done > by creating new byte array streams and Data Input/Output streams. That is > pretty wasteful, we can optimize this with Flink's own classes: > - {{DataInputSerializer}} > - {{DataOutputSerializer}} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
