In case of merge on read table, it exposes near-real time data(few mins) by merging the base and delta files of the latest file slice on-the-fly. For copy on write table, it provides a drop-in replacement for existing parquet tables, while providing upsert/delete and other write side features. -- **Incremental Queries** : Queries only see new data written to the table, since a given commit/compaction. This effectively provides change streams to enable incremental data pipelines. -- **Read Optimized Queries** : Queries see the latest snapshot of table as of a given commit/compaction action.

By default, this produces the latest + snapshot of the changes since a given point in timeline. + - ***Incremental Queries(CDC)*** : These are a subtype fo Incremental queries, where queries see all changed data since + a given commit/compaction as opposed to latest state of changed data. This enables full cdc style query use cases + allowing to see before and after images of the changes along with operations that caused the change. +- **Read Optimized Queries** : Queries see the latest snapshot of table as of a given commit/compaction action. Exposes only the base/columnar files in the latest file slices and guarantees the same columnar query performance compared to a non-hudi columnar table. +- **Bootstrap Queries** : Queries see the latest snapshot of a bootstrapped Hudi table as of a given commit/compaction action.
