> Key: HUDI-9581
> URL: https://issues.apache.org/jira/browse/HUDI-9581
> Project: Apache Hudi
> Issue Type: New Feature
> Reporter: Lin Liu
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.1.0

>
> FG reader does not support point lookup by default. So after integration with
> MDT, there is a behavior difference caused.
> 1. LogScanner allows on-demand read for Hfile data block only (not for Avro,
> Parquet); in which case the keys are pushed down into native hfile reader
> that filters records during the internal scan. FG reader uses full-scan by
> default, which means hfile reader iterates all records, and does filtering
> outside of the native hfile reader.
> 2. LogScanner enables point lookup for all partitoins but Files partition. FG
> reader does not allow on-demand for all partitions.
> Therefore, we should fix this behavior change.
