Thomas Groh resolved BEAM-1860. ------------------------------- Resolution: Fixed Fix Version/s: Not applicable This is fixed as part of the broader push to get a meaningful Coder Hierarchy. > SerializableCoder should not extend DeterministicStandardCoder > -------------------------------------------------------------- > > Key: BEAM-1860 > URL: https://issues.apache.org/jira/browse/BEAM-1860 > Project: Beam > Issue Type: Bug > Components: sdk-java-core > Affects Versions: 0.6.0 > Reporter: Wesley Tanaka > Assignee: Thomas Groh > Fix For: Not applicable > > > Not sure if this is just a doc bug, but: > https://beam.apache.org/documentation/sdks/javadoc/0.6.0/org/apache/beam/sdk/coders/SerializableCoder.html > says: > SerializableCoder does not guarantee a deterministic encoding, as Java > serialization may produce different binary encodings for two equivalent > objects. > Yet > https://beam.apache.org/documentation/sdks/javadoc/0.6.0/org/apache/beam/sdk/coders/DeterministicStandardCoder.html > says: > A DeterministicStandardCoder is a StandardCoder that is deterministic, in the > sense that for objects considered equal according to Object.equals(Object), > the encoded bytes are also equal. > These sound like they conflict, and thus that SerializableCoder should not > extend DeterministicStandardCoder -- This message was sent by Atlassian JIRA (v6.3.15#6346)
