Udit Mehrotra updated HUDI-1508:
--------------------------------
Labels: blocker release-blocker (was: )
> Partition update with global index in MOR tables resulting in duplicate
> values during read optimized queries
> ------------------------------------------------------------------------------------------------------------
>
> Key: HUDI-1508
> URL: https://issues.apache.org/jira/browse/HUDI-1508
> Project: Apache Hudi
> Issue Type: Bug
> Reporter: Ryan Pifer
> Priority: Major
> Labels: blocker, release-blocker
>
> The way Hudi handles updating partition path is by locating the existing
> record and performing a delete on the previous partition and performing
> insert on new partition. In the case of Merge-on-Read tables the delete
> operation, and any update operation, is added as a log file. However since an
> insert occurs in the new partition the record is added in a parquet file.
> Querying using `QUERY_TYPE_READ_OPTIMIZED_OPT_VAL` fetches only parquet files
> and now we have the case where 2 records for given primary key are present
