-------------------------------------
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.
