Description

Today the hudi index lookup APIs only support a small set of data, meaning that the lookup set has to fit into the memory of a single machine. We need to change it to RDD based implementation.

Research direction

Start by reading the Hudi index lookup APIs and the linked HUDI-9515 issue, then trace how the current lookup set is held on a single machine. Done means the lookup uses an RDD-based implementation so the lookup set no longer needs to fit in one machine's memory; run the relevant index tests after identifying them.
