Subject [jira] [Updated] (BEAM-1231) Use well known coder types in Java for WindowedValue, GlobalWindow, and LengthPrefix
Date Thu, 29 Dec 2016 20:04:58 GMT

     [ https://issues.apache.org/jira/browse/BEAM-1231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Luke Cwik updated BEAM-1231:
----------------------------
    Description: 
Add support for using kind for well known coder types in Apache Beam for Java

The following specific cloud object representations for the following types should exist:
kind:pair (TupleCoder with two components)
kind:stream (IterableCoder with a single component)
kind:global_window (GlobalWindowCoder)
kind:length_prefix (A new type of coder which always encodes the length of the value type
as a prefix, has a single component)
kind:windowed_value (A wrapper coder with two components (value coder and window coder))

These changes are towards having a common binary representation for certain well known coders
across multiple languages.
