[jira] [Commented] (AVRO-1582) Json serialization of nullable fileds and fields with default values improvement.
[ https://issues.apache.org/jira/browse/AVRO-1582?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=16022951#comment-16022951 ] MihkelJ commented on AVRO-1582: --- We ran up against this issue recently, so I've created a standalone encoder from Zoltan Farkas' excellent ExtendedJsonDecoder, until this issue is resolved: https://github.com/Celos/avro-json-decoder It handles point b) from above, infers the value of missing fields from their defaults. The only advantage is that it doesn't require forked avro. > 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 > 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 (v6.3.15#6346)
