JingsongLi opened a new pull request #1293: URL: https://github.com/apache/iceberg/pull/1293
Fixes #1275 This is Proof of Concept (POC) for Flink reader. The Flink reader is essentially the same as Spark. - Flink `InputFormat` is similar to Hive (Hadoop) input format. Its splits are generated in the job manager. Therefore, an iceberg catalog loader is needed to obtain the Iceberg `Table` object. - Flink `TableFactory` and `TableSource` are similar to Spark `TableProvider` and `SparkScanBuilder`, It also provides projection push down `ProjectableTableSource` and filter push down `FilterableTableSource`. Work can be divided into: - (Ongoing) Flink: Using RowData to avro reader and writer #1232 - Introduce `IcebergCatalogLoader`. - Introduce `FlinkInputFormat`: implement SplitGenerator and RowDataReader. - Extract `TestAppendHelper` for testing. - Introduce `FlinkTableFactory` and `FlinkTableSource`. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
