[jira] [Comment Edited] (HIVE-8131) Support timestamp in Avro
[ https://issues.apache.org/jira/browse/HIVE-8131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16678651#comment-16678651 ]

--------------------------------------------------------
This change only supports timestamp-millis. Avro 1.8.2 also supports timestamp-micros. [https://avro.apache.org/docs/1.8.2/spec.html#Timestamp+%28microsecond+precision%29]
timestamp-micros should also be supported in hive AvroSerde because hive timestamps support nano second level precision.

One possibility is to support avro timestamp-millis and avro timestamp-micros in serialization. Avro Deserializer can map hive timestamp to timestamp-micros.
