Lukas Steiblys commented on AVRO-1582: -------------------------------------- We ran into the same issue when encoding JSON data. This was not a problem with the Python AVRO implementation so we only ran into this when switching to Java/Scala. Our plan is to use [~zolyfarkas] implementation until this can be merged into the main repo since we aren't planning to change our JSON format and add AVRO coupling. > Json serialization of nullable fileds and fields with default values > improvement. > --------------------------------------------------------------------------------- > > Key: AVRO-1582 > URL: https://issues.apache.org/jira/browse/AVRO-1582 > Project: Avro > Issue Type: Improvement > Components: java > Affects Versions: 1.8.0 > Reporter: Zoltan Farkas > Priority: Minor > Attachments: AVRO-1582-PATCH > > > Currently serializing a nullable field of type union like: > "type" : ["null","some type"] > when serialized as JSON results in: > "field":{"some type":"value"} > when it could be: > "field":"value" > Also fields that equal the the default value can be omitted from the > serialized data. This is possible because the reader will have the writer's > schema and can infer the field values. This reduces the size of the json > messages. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
