[jira] [Created] (FLINK-30483) Make Avro format support for TIMESTAMP_LTZ

-------------------------------------

             Summary: Make Avro format support for TIMESTAMP_LTZ
                 Key: FLINK-30483
                 URL: https://issues.apache.org/jira/browse/FLINK-30483
             Project: Flink
          Issue Type: Improvement
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
    Affects Versions: 1.16.0
            Reporter: Mingliang Liu


Currently Avro format does not support TIMESTAMP_LTZ (short for TIMESTAMP_WITH_LOCAL_TIME_ZONE) type. Avro 1.10+ introduces local timestamp logic type (both milliseconds and microseconds), see [spec||https://avro.apache.org/docs/1.10.2/spec.html#Local+timestamp+%28millisecond+precision%29]. As TIMESTAMP currently only supports milliseconds, we can make TIMESTAMP_LTZ support milliseconds first.

A related work is to support microseconds, and there is already work-in-progress Jira [[FLINK-23589]] for TIMESTAMP type. We can consolidate the effort or track that separately for TIMESTAMP_LTZ.
