> Make BulkFormat more extensible
> -------------------------------
>
> Key: FLINK-20174
> URL: https://issues.apache.org/jira/browse/FLINK-20174
> Project: Flink
> Issue Type: Improvement
> Components: Connectors / FileSystem
> Affects Versions: 1.12.0
> Reporter: Steven Zhen Wu
> Priority: Major
> Labels: stale-major
>
> Right now, BulkFormat has the generic `SpitT` type extending from
> `FileSourceSplit`. We can make BulkFormat taking the generic `SplitT` type
> extending from `SourceSplit`. This way, IcebergSourceSplit doesn't have to
> extend from `FileSourceSplit` and Iceberg source can reuse this BulkFormat
> interface as [~lzljs3620320] suggested. This allows Iceberg source to take
> advantages high-performant `ParquetVectorizedInputFormat` provided by Flink.
> [~sewen] [~lzljs3620320] if you are onboard with the change, I would be happy
> to submit a PR. Since it is a breaking change, maybe we can only add it to
> master branch after 1.12 release branch is cut?
> The other related question is the two `createReader` and `restoreReader`
> APIs. I understand the motivation. I am just wondering if the separation is
> necessary. if the SplitT has the CheckpointedLocation, the seek operation can
> be handled internal to `createReader`. We can also define an abstract
> `FileSourceSplitBase` that adds a `getCheckpointedPosition` API to the
> `SourceSplit`.
