Sean Policarpio created AVRO-2132: ------------------------------------- Summary: Avro IDL: Support dot ('.') character in property annotation names Key: AVRO-2132 URL: https://issues.apache.org/jira/browse/AVRO-2132 Project: Avro Issue Type: Improvement Components: java Affects Versions: 1.8.2 Reporter: Sean Policarpio
Unless there is a strong reason why names like @foo.bar can't be used as property annotations in IDL, I propose an enhancement to the IDL parser to allow it. The major drive for this change comes from Kafka Connect; for a certain fields – namely timestamps – additional metadata must be present in the schema when certain consumers read the data (e.g. [the JDBC connector|https://github.com/confluentinc/kafka-connect-jdbc]). What I hoped when using IDL was to write the following for a record field: {code:java} union {null, @connect.version(1) @connect.name("org.apache.kafka.connect.data.Timestamp") long} queryTime;{code} so that the following would be available in the schemata: {code:java} { "name": "queryTime", "type": [ "null", { "type": "long", "connect.version": 1, "connect.name": "org.apache.kafka.connect.data.Timestamp" } ], "default": null }{code} Unfortunately, both connect.version and connect.name are unacceptable by the parser. The change for this is quite minimal as it can be based on AVRO-1267. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
