Hi,
I would like to verify that my understanding of parquet filter pushdown in
Drill (https://drill.apache.org/docs/parquet-filter-pushdown/) is correct.
Is it correctly understood that Drill does not support predicate push-down
for string fields when dictionary based string encoding is enabled?
sue of correctness for comparison is what makes the dependency on min-max
statistics by the Parquet library be unreliable.
