Reading parquet from S3

[Kirill Polunin]

Hi,
I'm writing an article about Apache Flink. I wanted to ask, does Apache
Flink supports reading Parquet files in Batching mode? Our team is going to
read parquet files from S3. I didn't find such page in flink's tutorials.
I will be grateful if you help, thank you

Hi Kirill,

For DataSet API, yes, we have "ParquetRowInputFormat",
"ParquetPojoInputFormat" and "ParquetMapInputFormat" [1].

For file system parquet files in table:
- Before 1.11, you can register a ParquetTableSource to batch table
environment with legacy planner.
- In 1.11, you can create file system table with parquet format, and
reading from SQL.

For hive in table, we support reading table with parquet format.
