Description

There may be a bug in TrinoPageSource.java appendTo method,

checkArgument(type.equals(TIMESTAMP_TZ_MILLIS));
Timestamp timestamp = (org.apache.paimon.data.Timestamp) value;
type.writeObject(
output, fromEpochMillisAndFraction(timestamp.getMillisecond(), 0, UTC_KEY));

when javaType is LongTimestampWithTimeZone.class, type is TIMESTAMP_TZ_MICROS but not TIMESTAMP_TZ_MILLIS?

Research direction

Open TrinoPageSource.java and inspect the appendTo method around the TIMESTAMP_TZ_MILLIS check and timestamp conversion. Compare that path with the LongTimestampWithTimeZone java type and TIMESTAMP_TZ_MICROS case; done means the connector handles the reported type without rejecting or mis-converting the value.
