JingsongLi opened a new pull request #11602: [FLINK-16912][parquet] Introduce 
table row write support for parquet writer
URL: https://github.com/apache/flink/pull/11602
 
 
   
   ## What is the purpose of the change
   
   Add row support for parquet writer.
   
   ## Brief change log
   
   - Add ParquetRowDataBuilder
   - Add ParquetRowDataWriter
   
   Timestamp support:
   - We only support INT96 bytes now, julianDay(4) + nanosOfDay(8). See 
https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#timestamp 
TIMESTAMP_MILLIS and TIMESTAMP_MICROS are the deprecated ConvertedType.
   - Timezone: provide a utcTimestamp bool, true using utc, false using local 
time zone. 
   
   Decimal support: 
   - isLegacyFormat is true: use FIXED_LEN_BYTE_ARRAY to support all decimal, 
this is compatible with hive and impala.
   - isLegacyFormat is false: use int32/int64/FIXED_LEN_BYTE_ARRAY to support 
all kinds of precision decimal. This is compatible with spark.
