Was able to verify that Hudi is writing out using `TIMESTAMP_MICROS` (which
presto does not seem to support) even though the source file is using
`TIMESTAMP_MILLIS`:
```
$ java -jar parquet-tools-1.8.2.jar schema source.parquet
message schema {
optional int32 order_id;
optional int32 order_qty;
optional binary customer_name (UTF8);
optional int64 updated_at (TIMESTAMP_MILLIS);
optional int64 created_at (TIMESTAMP_MILLIS);
}
$ java -jar parquet-tools-1.8.2.jar schema

message hoodie.orders.orders_record {
optional binary _hoodie_commit_time (UTF8);
optional binary _hoodie_commit_seqno (UTF8);
optional binary _hoodie_record_key (UTF8);
optional binary _hoodie_partition_path (UTF8);

optional int32 order_qty;
