> 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 [1]. 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.
