Kenneth Knowles resolved BEAM-703. ---------------------------------- Resolution: Fixed Fix Version/s: 0.3.0-incubating > SingletonViewFn might exhaust defaultValue if it's serialized after being > used. > -------------------------------------------------------------------------------- > > Key: BEAM-703 > URL: https://issues.apache.org/jira/browse/BEAM-703 > Project: Beam > Issue Type: Bug > Components: sdk-java-core > Reporter: Amit Sela > Assignee: Amit Sela > Priority: Minor > Fix For: 0.3.0-incubating > > > In > https://github.com/apache/incubator-beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/util/PCollectionViews.java#L267 > the defaultValue is set to null to avoid decoding over and over I assume. > If the defaultValue is accessed before the the SingletonViewFn is serialized, > it will exhaust the encoded value (assigned with null) while losing the > transient decoded value. > It'd probably be best to simply check if defaultValue is null before > decoding, so that decode will still happen just once, but the encoded data is > not lost. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
