Description

The new merge API in HoodieRecordMerger can only differentiate merge logic based on `OperationModeAwareness`, which introduces another layer of complexity. Instead, could we add a new argument of merge mode (pre-combine, or update) to the merge API for customized dedup (or merging of log records?), instead of using OperationModeAwareness?
