Description

Follow-up issue: #5 focuses on the datastream API implementation.

This feature mainly concerns the SQL/Table API implementation of the merge on read.

Use case/motivation

By implementing the merge-on-read feature in the SQL/Table API, we will improve ARCTIC-5 and make it more efficient and user-friendly for its users.

Describe the solution

  • Using the FlinkSplitPlanner.mergeOnReadPlan instead of planFullTable in the StaticArcticSourceEnumerator
  • Using the MergeOnReadIncrementalPlanner instead of ContinuousSplitPlannerImpl in the ArcticSourceEnumerator
  • Create the FlinkArcticMORDataReader to fetching the records by the MergeOnReadSplits in the RowDataReaderFunction, This UT is about FlinkArcticMORDataReader.
  • Support Flink1.12/1.14/1.15 versions
  • Add UTs
